When this creature enters, create a Lander token. (It's an artifact with "2, T, Sacrifice this token: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.")

Landfall — Whenever a land you control enters, creatures you control get +1/+1 and gain vigilance and haste until end of turn.
