Ability
When an enemy attacks you while you have the Heart of Cards equipped you will gain a status effect called "Card Shuffle" which lasts 10s. As the enemy continues to attack you you will gain more stacks of this buff (each enemy attack adds 1 stack and resets the buff timer to 10s). When it reaches 10 stacks the Card Shuffle buff will be removed and 10 cards will be shot at the enemy, each dealing 600k Deific Damage. This Damage is affected by alignment buffs and by critical chance, however stamps, talents, rings, and status effects aren't effective.
