Early Access notice: Slay the Spire 2 is actively updated by MegaCrit. Card balance shifts between patches, so tier positions may move. This list reflects the current EA build — check back after major patch notes drop.
Picking the right cards in Slay the Spire 2 is the difference between a winning run and floor 16 humiliation. Every draft decision compounds — a single S-tier pick early can define your entire route. But knowing which cards are actually strong, versus which ones only look powerful, is what separates experienced players from beginners.
This tier list covers every card in the current Slay the Spire 2 Early Access build for both the Ironclad and Silent characters. For each S-tier pick, we break down why it wins games — the synergies, the archetypes it enables, and the combos that make it oppressive. A-tier cards get short notes. B and C tier are listed for reference so you know what to skip or deprioritise.

How to Use This Tier List
This is a deck evaluation tool, not a pick order. Context matters more than tier rating in any given run. A C-tier card might be exactly what a specific deck needs; an S-tier card can be wrong if you are forced to draft it with no synergies.
Use these tiers to answer two questions during drafts:
- Is this card generically powerful? S and A-tier cards are strong in most decks regardless of archetype.
- Does this card fit what I am already building? A B-tier card that completes a synergy is often a better pick than an A-tier card that clashes with your kit.
Upgrade priority (covered later) is separate from tier position. Some C-tier cards are worth upgrading early because the upgrade changes their function entirely.
Ironclad Tier List
The Ironclad is built around Strength scaling, exhaust synergies, and block generation through aggressive play. At its best, an Ironclad deck multiplies Strength gains until each attack does triple-digit damage. Here is where every card lands in the current EA meta.
Ironclad S-Tier Cards
| Card | Cost | Effect | Why S-Tier |
|---|---|---|---|
| Demon Form | 3 | Power: +2 STR per turn | Infinite Strength scaling wins long fights |
| Whirlwind | X | Attack all enemies 3× per energy spent | Scales explosively with STR; clears and presses bosses |
| Limit Break | 1 Exhaust | Double your Strength | One card doubles all future damage; upgraded retains |
| Offering | 0 Exhaust | −6 HP, draw 3, +2 energy | Massive tempo swing; turns slow openers into wins |
| Corruption | 3 | Skills cost 0, Skills exhaust | Enables infinite cycle combos with Feel No Pain + Dark Embrace |
Demon Form is the Ironclad’s best late-game win condition. After three turns of passive Strength gain you are doing 20+ damage on a base Twin Strike. Upgraded, it grants +2 STR immediately on play rather than waiting. Slot it into any deck willing to survive three turns of build-up — which most Act 3 decks can do with proper block. Archetype: Strength stacking, any build with Inflame or Spot Weakness already in hand.
Whirlwind is the Ironclad’s best scaling attack. Spending 3 energy means 9 hits at whatever your STR-boosted damage is. Drop it into a deck with Demon Form and Limit Break and you are one-shotting elite packs. It also handles multi-enemy rooms cleanly, which the Ironclad normally struggles with. Archetype: STR scaling, energy-ramp decks.
Limit Break combined with any Strength base turns decent damage into devastating numbers. The exhaust cost means one use per fight unless you have Sentinel or Offering to recycle energy. Upgraded, it retains in hand so you can hold it for the perfect moment. Combos: Demon Form + Limit Break + Whirlwind is the Ironclad’s highest damage ceiling.
Offering is the best energy burst card in the game. Losing 6 HP is trivial once you have Reaper or decent block to recover. In exchange you get three cards and two energy on top of your normal energy — effectively a near-free extra turn inside your turn. It accelerates every archetype. Never skip it in Act 1 unless your HP is already critical.
Corruption makes skills free and exhausts them. Alone this is awkward. With Feel No Pain (block every exhaust) or Dark Embrace (draw every exhaust) it creates an infinite loop. A Shrug It Off costs 0 under Corruption, exhausts, triggers Feel No Pain for 6 block, and Draw draws another card. One Corruption activates an entire engine. Archetype: Exhaust synergy, the Ironclad’s most skill-expression-heavy build.
Ironclad A-Tier Cards
| Card | Notes |
|---|---|
| Feel No Pain | 6 block per exhaust; mandatory in exhaust builds; good filler in any deck |
| Impervious | 30 block for 2 energy is generically incredible; exhaust cost prevents stacking |
| Fiend Fire | Deals damage per card exhausted; pairs with Battle Trance for a hand dump finish move |
| Body Slam | Damage equals your block total; disgusting with Barricade or high passive block |
| Second Wind | Exhaust all non-attacks for 5 block each; powerful deck-slimming and block tool |
| Reaper | Lifesteal on hit; outstanding self-sustain, especially post–Demon Form |
| Juggernaut | 3 random damage whenever you gain block; combos with high-block turns |
| Dark Embrace | Draw 1 per exhaust; engine enabler alongside Corruption |
Ironclad B-Tier Cards
Solid, playable cards that round out most decks: Bash (reliable Vulnerable application), Shrug It Off (block + draw on 1 energy), Inflame (+2 permanent STR), Cleave (AOE for elite rooms), Battle Trance (draw 3 at the cost of future draws), Hemokinesis (card draw with HP cost), True Grit (block + random exhaust), Entrench (double current block), Iron Wave (5/5 split for 1 energy).
Ironclad C-Tier Cards
Situational or weak: Sword Boomerang (random targeting hurts single-target damage), Thunderclap (Vulnerable AOE but low damage), Reckless Charge (Wounds pollute your deck), Havoc (plays top card — too unreliable), Headbutt (recovers a card — rarely worth 1 energy).
Silent Tier List
The Silent wins through poison accumulation, shiv generation loops, and card draw efficiency. Unlike the Ironclad’s brute force approach, Silent decks build engines — self-sustaining combos that generate infinite block or deal damage through debuffs rather than raw hits.
Silent S-Tier Cards
| Card | Cost | Effect | Why S-Tier |
|---|---|---|---|
| Noxious Fumes | 1 | Power: Apply 2 Poison at turn start | Passive, infinite, requires no attacks to scale |
| Catalyst | 1 Exhaust | Double target’s Poison | One card turns 30 poison into 60; upgraded triples |
| Infinite Blades | 1 | Power: Add 1 Shiv to hand each turn start | Free attacks every turn; scales with Accuracy and After Image |
| Accuracy | 1 | Power: Shivs deal +4 damage | Turns each free Shiv into a real attack; stacks with multiples |
| After Image | 1 | Power: Gain 1 block per card played | Shiv builds play 10+ cards per turn — 10+ block per turn for free |
Noxious Fumes is the Silent’s most efficient win condition. It costs 1 energy, requires no further card plays to deal damage, and it scales every turn. By turn 5 you have applied 10 poison stacks passively. The enemy loses HP at the end of each turn with zero additional input from you. In high-Act runs it combines with Catalyst to end bosses in 2–3 turns from a Poison base the Fumes have been building for 10 turns. Archetype: Poison stacking. Works in any deck as a side wincon; mandatory in dedicated poison builds.
Catalyst multiplies existing Poison stacks. Upgraded, it triples them. If Noxious Fumes has stacked 25 Poison and you play two Catalysts, that enemy is taking 75 damage at the end of the turn. One of the highest single-card damage ceilings in the game. Its exhaust cost is the only limiter — you get one shot per fight. Combo sequence: Noxious Fumes (stack for several turns) → Catalyst (double) → Catalyst (upgraded, triple) → pass turn while enemy dies.
Infinite Blades enables the Silent’s shiv archetype single-handedly. A free attack every turn is already valuable; once you add Accuracy (each shiv hits harder) and After Image (each shiv played = 1 block), you are generating 5– 10+ block per turn from a single Power card. The shivs also proc Envenom for poison stacking and Caltrops for chip damage return. Archetype: Shiv generation, exhaust-on-attack builds.
Accuracy is near-mandatory in shiv builds. Each copy stacks separately, so two Accuracy cards means +8 damage per shiv. With Infinite Blades giving you a free shiv every turn, two Accuracy copies = 8 extra damage per turn with no card plays. Archetype: Shiv builds only — dead weight without shiv generation.
After Image is the Silent’s best defensive card. Playing 10 cards in a turn (easy in shiv decks) gives 10 block for free. It converts card draw efficiency into survivability. In builds with Burst or high-draw engines, After Image can generate 30–40 block in a single turn without a single dedicated block card in the deck. Archetype: Shiv builds, high-draw decks, any engine-heavy kit.
Silent A-Tier Cards
| Card | Notes |
|---|---|
| Wraith Form | Intangible for 3 turns; take 1 damage from all hits; powerful but Dexterity drain kills block |
| Die Die Die | AOE 13×3; exceptional against multi-enemy rooms; best AOE in Silent’s kit |
| Burst | Next skill plays twice; paired with Catalyst or Crippling Cloud = double effect for 1 cost |
| Envenom | Power: Attacks apply 1 Poison; turns every shiv into a poison applicator |
| Corpse Explosion | On-kill AOE from Poison stacks; wipes rooms once poison is established |
| Predator | Draw 2 on kill; outstanding card draw that rewards aggressive play |
| Bullet Time | Cards cost 0, no draw; S-tier in cycle decks, A-tier generally |
| Choke | Attack that applies Weak; upgraded Weak lasts longer — strong single-target debuff |
Silent B-Tier Cards
Reliable cards that fill specific roles: Blade Dance (3 shivs for 1 energy, great in accuracy builds), Backflip (3 block + draw 2 for 2 energy, efficient cycle card), Expertise (draw up to 6 cards, fantastic in low-hand-size decks), Dodge and Roll (block now + block next turn for 1 energy), Flying Knee (Vulnerable application, then energy refund when played next turn), Heel Hook (energy refund on Weak enemy), Well Laid Plans (retain power — excellent in combo decks that need to hold cards), Caltrops (thorns for multi-hit enemies).
Silent C-Tier Cards
Narrow or weak: Dagger Spray (low damage, random targeting), Glass Knife (decreasing damage each use — falls off fast), Deflect (4 block for 0 is low ceiling, not scalable), Acrobatics (draw 3 discard 1 — decent but competes with stronger draw), Prepared (draw 1 discard 1 — too low value).
Colorless Cards Tier List
Colorless cards appear in shops and rewards for all characters. They are often overlooked but some are run-defining picks.
| Tier | Card | Notes |
|---|---|---|
| S | Apotheosis | Upgrade every card in your deck; one purchase is worth 10 campfire stops |
| S | Bandage Up | Heal 4 HP on exhaust; free value in exhaust-heavy decks; the best colourless in exhaust builds |
| A | Enlightenment | Reduce card costs for the turn; useful as tempo when expensive cards clog hand |
| A | Finesse | 2 block + draw 1 for 0 energy; free cycling that also defends |
| A | Master of Strategy | Exhaust for 3 gold; strong in Act 1 when gold is scarce |
| B | Blind | Apply Weak to all enemies; reliable opener against multi-enemy rooms |
| B | Dark Shackles | −9 STR to enemy this turn; boss-specific tool; incredible against Strength-scaling elites |
| C | Trip | Vulnerable all; niche, displaced by character-specific Vulnerable tools |
| C | Swift Strike | 7 damage for 0; filler, not exciting in any archetype |
Curse Cards to Avoid
Curses add dead cards to your deck. Some curses are tolerable; others are deck-destroying. Never take a curse from an event unless the reward is run-changing (a boss relic, three rare picks, or a key upgrade).
- Regret — worst curse; −1 HP per card in hand at end of turn. In a draw-heavy deck this drains 5–6 HP every turn.
- Pain — −1 HP per card played. Silent shiv decks play 10+ cards per turn. This is −10 HP per turn.
- Decay — −2 HP at end of turn; constant drain that compounds over long runs.
- Normality — play max 3 cards per turn. Cripples engine decks and combos outright.
- Shame and Necronomicurse — survivable but always junk in your draw pile.
Trap Cards: What Looks Good but Underperforms
Some cards have impressive stat lines that hide serious weaknesses. These are the most common drafting mistakes.
Sever Soul (Ironclad) — deals 16 damage and exhausts all non-attack cards. Sounds like a power move. In practice, you exhaust the potions, relics, and defensive cards you needed. The damage is not high enough to justify the hand destruction in most fights.
Glass Knife (Silent) — starts at 8+8 damage but permanently drops by 2 each use. After three plays it is barely competitive with a base Strike. In a long boss fight it becomes dead weight. Never prioritise it.
Reckless Charge (Ironclad) — 7+7 split with a Wound added to your discard. Wounds are shuffled into your deck and clog draws with dead cards. Against any fight that lasts more than five turns, the Wound accumulation costs you more in draw quality than the damage is worth.
Sword Boomerang (Ironclad) — three random hits at 3 each sounds like 9 damage but hits random targets. Against single enemies with multiple hitboxes it is inefficient; against groups it refuses to focus-fire. Reliable damage, it is not.
Grand Finale (Silent) — deals 50 damage if the draw pile is empty. Devastating when it works. But engineering an empty draw pile in a real run is far harder than theory suggests, and if you play it with cards remaining it deals zero. Occasional S-tier ceiling, consistent B/C performance.
Upgrade Priority List
Campfire stops are scarce. Here are the cards that benefit most from an upgrade, in rough priority order:
- Demon Form — upgraded grants +2 STR immediately on play instead of next turn. Turns a great card into a time machine.
- Catalyst — upgraded triples Poison instead of doubling. This is a 50% damage increase on your entire poison pool in one upgrade.
- Limit Break — upgraded retains in hand. You can wait for the perfect STR doubling moment every turn instead of committing on a suboptimal board.
- Noxious Fumes — goes from 2 Poison per turn to 3. Over a 10-turn fight that is 10 additional stacks — significant against high-HP bosses.
- Corruption — upgraded makes skills retain instead of exhausting. This enables replaying key skills, changing the card from a one-and-done enabler to an ongoing engine.
- Infinite Blades — generates 2 shivs per turn instead of 1. With Accuracy in play this doubles your passive damage output.
- Offering — upgraded reduces the HP cost from 6 to 3. Not mandatory but preserves HP for tougher encounters.
- Impervious — goes from 30 to 40 block. In Act 3 boss fights the extra 10 block can absorb an entire attack.
- Bash — upgraded deals 10 damage and applies 3 Vulnerable instead of 2. First-turn Bash into upgraded Bash sets up massive follow-up damage.
- Feel No Pain — block per exhaust goes from 3 to 4. In Corruption builds that exhaust 6–8 cards per turn, this is 6–8 extra block per fight.

Frequently Asked Questions
Is this tier list accurate for the current Early Access build?
Yes — this list is based on the current EA version. MegaCrit releases balance patches regularly during Early Access, so specific numbers can change. S-tier cards tend to remain strong through patches because their power comes from synergy potential, not raw numbers. Check patch notes after major updates for any card reworks.
Does the tier list change depending on which character I am playing?
Yes. Ironclad and Silent tier lists are separate because their card pools do not overlap. Colorless cards are the only cross-character picks — their tier positions hold for both characters, though specific synergies (Bandage Up in exhaust builds) may shift their value.
Should I always take the highest-tier card in a reward?
No. Tier reflects generic power, not draft fit. If you have an S-tier Ironclad card that clashes with your current synergies and a B-tier card that completes your engine, take the B-tier card. Deck coherence beats individual card quality in Slay the Spire 2.
When should I skip a card reward entirely?
Skip rewards when all options would bloat your deck without adding win conditions. A lean 10-card deck beats a 20-card deck with no synergy. Skipping is always the correct decision if none of the three options improves your win condition or fills a defensive gap.
What is the strongest archetype in Slay the Spire 2 right now?
Both Corruption-exhaust (Ironclad) and Noxious Fumes-Catalyst (Silent) are the highest-ceiling archetypes in the current EA meta. Silent poison scales better into Act 3 bosses; Ironclad Corruption builds are faster but require precise play. Both reward understanding the tier lists in this guide.
