Nissa of Shadowed Boughs (283)

Landfall — Whenever a land you control enters, put a loyalty counter on Nissa.
: Untap target land you control. You may have it become a 3/3 Elemental creature with haste and menace until end of turn. It's still a land.
: You may put a creature card with mana value less than or equal to the number of lands you control onto the battlefield from your hand or graveyard with two +1/+1 counters on it.
