Card Sharp

As a bonus action you arrange a deck into a fan and imbue it with mystical power, transforming them into keenly-edged cards. It counts as a magical Finesse weapon that you are proficient with. On a successful strike against a target, it deals 1d8 slashing damage. You use your spell casting MOD, instead of Strength or Dexterity, for the attack and damage rolls. This benefit lasts for 1 minute or until you dismiss it as a bonus action.
