Give one of your units Killer.
Card sounds may differ from in-game as they get updated.
Killer - A unit with Killer can make one special attack directly against an enemy unit. This can be done the turn it's played, and can target any unit, regardless of Flying, Aegis, or other special abilities.
Warp - You can see cards with Warp when they are on top of your deck, and you can play them as if they were in your hand.
