Esau, the Red Hunter

Haste, Trample.
Whenever Esau, the Red Hunter attacks or
becomes blocked, you may sacrifice another
creature. If you do, put X +1/+1 counters on
Esau, where X is the sacrificed creature's power.
At the beginning of your end step, if Esau's
power is 10 or greater, you lose the game.
... Esau became a skillful hunter, a man of the open country - Gen 25:27
