MTG Mono Green Aggro Deck by erkhrmnsn

Whenever another creature you control enters or dies, if that creature's power is greater than this creature's, put a +1/+1 counter on this creature. As long as this creature has three or more +1/+1 counters on it, it has trample.

({G/W} can be paid with either {G} or {W}.) If an instant or sorcery card would be put into a graveyard from anywhere, exile it instead.

{G}: Exile target card from a graveyard. If it was a creature card, put a +1/+1 counter on this creature and you gain 1 life.

Haste Undying (When this creature dies, if it had no +1/+1 counters on it, return it to the battlefield under its owner's control with a +1/+1 counter on it.)

Enchant creature Enchanted creature gets +2/+0 and has trample. When this Aura is put into a graveyard from the battlefield, return it to its owner's hand.

Kicker {G} (You may pay an additional {G} as you cast this spell.) Target creature can't be the target of spells or abilities your opponents control this turn. If this spell was kicked, that creature gets +4/+4 until end of turn.
