Garza

Trample, Devour 2 (As this enters the battlefield,
you may sacrifice any number of creatures. This creature enters the battlefield with twice that many
+1/+1 counters on it.)
Whenever a creature is put into a graveyard from anywhere, put a +1/+1 counter on Garza.
Remove a +1/+1 counter from Garza: It deals one
damage to every creature and player.
