Tier List

Slay the Spire 2 Card Tier List

Slay the Spire 2 introduces dozens of new mechanics, cards, and two brand-new characters (Regent and Necrobinder), reshaping the card power landscape dramatically. This tier list ranks key cards across all characters into five tiers — S, A, B, C, and D — helping you quickly identify which cards to prioritize and which to skip.

Rankings reflect real performance at high Ascension levels (15+), taking into account immediate impact, scaling potential, synergy flexibility, and overall reliability. S-tier cards define the meta — consider building around them when offered. D-tier cards should generally be skipped unless no alternatives exist.

The meta is still evolving. As patches roll out and the community refines strategies, these rankings will be updated. The best players don't just chase S-tier cards — they understand what their deck needs and what problem each card solves in the current run.

S

S-Tier — Game Changers

Cards that define entire strategies. If offered these, build around them. They provide unmatched value, scaling, or synergy potential.

CorruptionIronclad

Makes all skills free. Paired with Dead Branch, becomes the strongest combo in the game.

CatalystSilent

Doubles or triples poison stacks. Ends boss fights instantly.

Echo FormDefect

Doubles card effects each turn. Scales any strategy into absurd value.

FeedIronclad

Permanent max HP gain on kills. The longer the run, the tankier you get.

LessonSilent

Adds a permanent upgraded card to your deck each time played.

A

A-Tier — Excellent Picks

Strong, reliable cards that fit into most decks. They provide excellent value without requiring specific synergies to perform.

ImperviousIronclad

Highest block-per-card ratio in the game. Exhausts but saves runs.

AdrenalineSilent

Free draw + energy. Zero-cost acceleration for any Silent deck.

Biased CognitionDefect

Instant +4 or +5 focus. Pairs perfectly with Orange Pellets or Core Surge.

OfferingIronclad

Draws 5, gives 2 energy, costs 6 HP. The best acceleration card.

Wraith FormSilent

3 turns of near-invincibility. Often enough to end any fight.

B

B-Tier — Solid and Situational

Good cards that perform well in the right deck. They are never a bad pick but rarely define a run on their own.

Demon FormIronclad

Scales Strength each turn but costs 3 energy. Requires draw and block support.

FootworkSilent

Permanent Dexterity boost for better block. Core defensive scaling.

ElectrodynamicsDefect

Applies lightning to all enemies. Excellent for AoE hallway fights.

Spot WeaknessIronclad

Conditional Strength gain. Reliable in most fights with multi-hit attacks.

GlacierDefect

Great frost generation + block. Foundational for any frost deck.

C

C-Tier — Niche or Awkward

Cards with narrow use cases. They can shine in the right deck but often sit in hand or require too much setup.

Searing BlowIronclad

Only worthwhile if you commit multiple upgrades. A meme, not a strategy.

Grand FinaleSilent

Requires exactly 0 cards in draw pile. Hard to set up consistently.

ClawDefect

Scales per Claw played. Fun when it works, but inconsistent without support.

Meteor StrikeDefect

Expensive but creates 3 Plasma. Only works with energy generation support.

D

D-Tier — Usually Skip

Cards that underperform in most situations. They are either too slow, too conditional, or outclassed by alternatives.

ClashIronclad

Only playable if hand has no Skills. Restrictive for marginal damage.

SetupSilent

Reduces card cost next turn. Too slow for most fights and expensive to play.

HeatsinksDefect

Draws on power play. Requires heavy power investment to be valuable.

ReprogramDefect

Sacrifices orbs for physical stats. Fights against Defect's core design.

Tier Criteria

S-Tier: Meta-defining. These cards stand out regardless of deck direction. Consider building around them when offered.

A-Tier: Strong and reliable. Excellent in most decks, performing well without heavy support.

B-Tier: Solid but not core. Good in the right deck but rarely define a run on their own.

C-Tier: Situational. Can shine in the right build but have narrow use cases.

D-Tier: Usually skip. Too slow, too conditional, or outclassed by alternatives.

Note: Rankings are based on high Ascension play. Casual runs and specific gimmick decks may have different valuations.

Frequently Asked Questions

What do S/A/B/C/D tiers mean?▼

S-Tier cards are the most powerful — they define strategies and can single-handedly win runs. A-Tier cards are excellent picks that fit almost any deck. B-Tier cards are solid and perform well with the right support. C-Tier cards are niche — they require specific decks or conditions to shine. D-Tier cards are usually not worth picking unless no alternatives are available.

Which character has the strongest card pool in STS2?▼

The Ironclad and Silent remain extremely strong, with well-established S-tier strategies (Corruption + Dead Branch for Ironclad, Catalyst-based poison for Silent). Defect's orb scaling with focus is also S-tier when assembled. The new Regent and Necrobinder characters have promising emerging strategies, but their card pools are still being explored by the community.

How often is the tier list updated?▼

This tier list reflects the current understanding of the STS2 meta. As the game receives patches and the community discovers new strategies, we update the rankings accordingly. Major patches and significant community discoveries trigger a review of all tier placements.

Should I always take S-tier cards?▼

Not always. A card is only valuable if it fits your deck's direction and solves a real problem. An S-tier card that conflicts with your current build may be worse than an A-tier card that synergizes perfectly. Context matters — consider your deck's current needs, energy curve, and win condition before choosing.
