First strike, Trample, Haste

At the beginning of combat on your turn, if Aberoff is in your command zone, you may put it onto the battlefield. If you do, sacrifice it at end of combat. Then pay {1} for each time Aberoff entered the battlefield this game. If you can't, sacrifice Aberoff.

Aberoff is unaffected by commander tax and whenever Aberoff deals damage to an opponent, it doesn't count as commander damage.

At the beginning of your end step, put a +1/+1 on Aberoff.
