Feast of the Wild

Whenever a creature you control deals combat damage to a player, Put a hunger counter on Feast
of the Wild.

{r}{g}: You may remove any number of hunger counters from Feast of the Wild. If you do, create that many 2/2 green Wolf tokens.

As the moons pass, the hunger becomes greater and greater until finally it's insatiable and they feast on whatever is in their way.
