Ashcoat of the Shadow Swarm

Whenever Ashcoat of the Shadow Swarm attacks
or blocks, other Rats you control get +X+X until
end of turn, where X is the number of Rats you control.
At the beginning of your end step, you may mill
four cards. If you do, return up to two Rat
creature cards from your graveyard to your hand.
