Kodama of the West Tree
Legendary Creature — Spirit
Reach
Modified creatures you control have trample. (Equipment, Auras you control, and counters are modifications.)
Whenever a modified creature you control deals combat damage to a player, search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Rulings
An Aura controlled by an opponent does not cause a creature you control to be modified.
A creature with a counter on it is considered modified no matter what kind of counter it is or which player put it on that creature.
A creature that is equipped is considered modified no matter who controls the Equipment that's attached to it.
Only creatures can be modified. If a modified creature stops being a creature, it is no longer considered modified.
