Lom, Lord of Sifters

Menace, Trample
If you would draw a card, instead mill four
cards, then return a card milled this way
from your graveyard to your hand.
Whenever a card leaves your graveyard, put a
+1/+1 counter on Lom, Lord of Sifters.
"Dat dere's pretty trinket, I'll let ya feel Big Bat
on yer' noggin for it."
