Moc, Jungle Predator

Wither, lifelink
Whenever you cast a spell that targets a creature
you control, you may have that creature fight
another target creature.
When a creature you control dies, you may put
up to three target cards from your graveyard
on the bottom of your library in any order. This ability triggers only once each turn.
At the beginning of each end step, if a creature
died this turn, you may pay {b/g}. If you do, draw a
card.
