The Elk, God of Forest

Partner with The Crow, God of Mountains
Trample, indestructible
As long as you don't control The Elk's Heart,
The Elk is not a creature.
When The Elk enters the battlefield, create
The Elk's Heart.
Whenever one or more creatures you control
deal combat damage to an opponent, search
your library for a forest card and put it onto
the battlefield, then shuffle.
