Slay the Spire 2 Colorless Cards
A Slay the Spire 2 colorless card guide for evaluating flexible picks, shop decisions, and cross-character utility.
Quick answer
Colorless card pages should answer whether a flexible card is actually worth the cost or reward slot in the current patch.

What to check first
Use this page as a practical search-intent answer first, then follow the related database links for deeper card, relic, character, boss, and patch context.
- Compare universal utility against character-specific synergy.
- Mark shop-only value separately from reward value.
- Link strong colorless cards into the card tier list.
Streak footage needs sample labels
A colorless card that performs well in a streak can still be context-dependent. The guide should record whether the card solved an immediate fight, completed an engine, or was simply affordable because the deck was already strong.
- Separate universal utility from win-more payoff.
- Label whether the card was a shop buy, reward, or special source.
- Link standout colorless cards back to the card tier list before changing global advice.
Shop picks need a gold test
Many colorless cards are not free picks. If the card comes from a shop, it competes against removal, potions, relics, and character cards. A flexible card is worth buying only when it solves a problem better than those alternatives.
- Compare colorless cards against the best removal or potion available.
- Buy universal utility when the deck lacks draw, block, or emergency damage.
- Avoid expensive colorless payoff when the deck still needs basic survival tools.
