Woodborn Behemoth
Duel Decks: Nissa vs. Ob Nixilis — uncommon
Creature — Elemental
As long as you control eight or more lands, Woodborn Behemoth gets +4/+4 and has trample. (It can deal excess combat damage to the player or planeswalker it's attacking.)
It carries the hopes of Zendikar's embattled wilds on its mighty boughs.
