Savage Wilds

If you control two or more other lands, Savage Wilds
enters the battlefield tapped.

{t}: Add {g}.

{3}{g}: Savage Wilds becomes a 4/4 green Dinosaur
creature with trample and reach until end of turn. It’s
still a land.

Whenever Savage Wilds deals combat damage to a
player, put a +1/+1 counter on target creature you control.
