What is Mummified Hand?
Playing Powers can make a hand card free for the turn.
This reference covers gameplay decisions in the original Slay the Spire. Character-specific options and relic synergy can change how useful an item is, so consider your current deck, health, upcoming enemy and available resources before applying a strategy.
When and how to use it
Reward frequent Powers and sequencing that exposes high-cost cards.
What to avoid
Random cost reduction is not a guaranteed specific-card discount.
