Moria, the Fanged Snow

When Moria enters the battlefield, you may put a +1/+1 counter on it. If you don't, Moria gains haste until end of turn.
Whenever a creature you control attacks, if that creature has a +1/+1 counter on it, create a 2/2 green Wolf creature token that's tapped and attacking. Exile those tokens at end of combat.
Whenever Moria deals combat damage to a player, distribute that many +1/+1 counters amongst creatures that attacked this turn.
