Scurry of Squirrels [BLC-33]

Myriad, myriad (Whenever this creature attacks, for each opponent other than defending player, you may create a token that's a copy of this creature that's tapped and attacking that player or a planeswalker they control. Then do it again. Exile the tokens at end of combat.) Whenever Scurry of Squirrels deals combat damage to a player, put a +1/+1 counter on target creature you control.
