Mole

Mole is a creature type used for cards that depict mammals adapted to a subterranean lifestyle with cylindrical bodies, and small, inconspicuous ears and eyes.

The first creature to bear the type is Graf Mole from Shadows over Innistrad. These star-nosed mole beasts have a keen smell that draws them to the unnatural.
