Summon: Give a unit Quickdraw.
Card sounds may differ from in-game as they get updated.
Quickdraw - Units with Quickdraw kill blockers before they can deal damage back. Note that Quickdraw only works while attacking, not while blocking.
Summon - Does something when played
Corrupted - When a unit with Corrupted dies, a 0 strength Nightmare Shade is played. Shades have the ability to sacrifice themselves by paying their corrupted cost to play the starting unit's Summon ability. Shades lose 1 health at the end of each of your turns.
