Prototerrusaur

When Prototerrusaur enters the battlefield, you may have Plant creatures you control get +0/+3 until end of turn.
Whenever Prototerrusaur blocks or dies, you may have an opponent gain 2 life. If you do, search your library for a basic land card and put that card onto the battlefield tapped. Then shuffle your library.
This isn't even its final form.
