Sunstar Expansionist (EOE-041) [Edge of Eternities]

When this creature enters, if an opponent controls more lands than you, 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, this creature gets +1/+0 until end of turn.
