Thorg

This creature's power and toughness are each equal to the number of lands you control that are Islands, Forests, or Swamps.

Whenever you search your library for a basic land card, you may search for a land that has that basic land type instead.

Whenever an Island you control enters, you may surveil 2.
Whenever a Forest you control enters, you may play an additional land this turn.
Whenever a Swamp you control enters, you may return target land from your graveyard to your hand.
