Ashvala, the Raging World

Menace, reach, trample
Each land you control is a 4/4 Elemental creature
with menace, reach, and trample that's still a land.
Whenever a land card is put into your graveyard
from the battlefield, destroy target artifact or enchantment you don't control.
When Ashvala, the Raging World dies, put it on
top of your library.
