Savage Deviljho

Devour 2 (As this enters the battlefield, you may sacrifice any number of creatures. This creature enters
the battlefield with 2 +1/+1 counters on it for each of
those creatures.)
{1}{b/r}, sacrifice another creature you control: Put
a +1/+1 counter on Savage Deviljho. Then, if its
power is 15 or greater, it gains trample and ingest
until end of turn. (Whenever this creature deals
combat damage to a player, that player exiles the top
card of their library.)
