Invasion of Lorwyn // Winnowing Forces

Battle — Siege // Creature — Elf Warrior

Mana cost {4}{B}{G}

(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, then cast it transformed.) When this Siege enters, destroy target non-Elf creature an opponent controls with power X or less, where X is the number of lands you control. // Winnowing Forces's power and toughness are each equal to the number of lands you control.
