On The Prowl

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.

Hunt - The enemy player will discard the specified number of cards from the top of their deck and the hunter receives +1/+1 for each non-power discarded that way. Any power discarded this way, you will draw an Advantage that gives +1 power for each.
