Earth Raker

Trample.
Whenever Earth Raker attacks, you may search
your library for a land and put it on the
battlefield tapped. If you don't, sacrifice a land
and draw 3 cards.
Whenever Earth Raker attacks, but doesn't deal
combat damage to a player or planeswalker,
search your library for a creature card. Shuffle
your library and put that card on top.
