Skargin, the Devourer

Devour 3 (As this enters the battlefield, you may sacrifice any number of creatures. This creature enters
the battlefield with three times that many +1/+1
counters on it.)
{2}{b/g}{b/g}: Exile target creature card from a
graveyard. Create a token that's a copy of it,
except it's a 1/1 green Ooze with Devour 1.
If Skargin, the Devourer would be destroyed, regenerate it.
