Drifter

Bloodthirst 2 When a creature you don’t control dies during combat on your turn, put a +1/+1 on Drifter, then you may have Drifter fight target creature you don’t control. If that creature dies this way, put a +1/+1 counter on Drifter. {flavor}“My existence is like gravity or time. A concept that you fear, but you cannot escape. I simply am.”
