From Ironclad to Necrobinder, we pinpoint the S-tier picks that turn shaky decks into Heart-crushing engines.
Picking the right cards in Slay the Spire 2 turns a shaky run into a powerhouse. Five classes come with distinct mechanics—Strength stacking, Poison, Orbs, Star forging, and Soul engines—but not all options are equal. Some cards define entire strategies on their own.
The gap between a deck that stalls in Act 2 and one that sweeps the Heart often comes down to a few key picks. Knowing the heavy hitters lets you avoid dead draws and commit to a winning archetype early.
In this guide we’ll cover the best cards for every class, from the Ironclad’s game-breaking staples to the Necrobinder’s lethal endgame payoffs.
Ironclad best cards

– Immovable: Power that doubles Block from the first card you play each turn.
– Break: Ancient 1-cost attack dealing 20 (30) damage and 5 (7) Vulnerable.
A-Tier
– Vicious: Draw 1 (2) cards whenever you apply Vulnerable to an enemy.

– Suppress: Ancient Innate 0-cost, deals 11 (17) damage and applies 3 (5) Weak.
A-Tier

Payoff and damage

– Soul Storm: Finisher that deals damage scaling with Souls in your Exhaust pile.
– End of Days: Rare, instantly kills enemies whose Doom stacks equal or exceed their current HP.
Energy
