Everek, Seeker of Horizons

Whenever Everek enters or attacks, explore.
(Reveal the top card of your library. Put that
card into your hand if it's a land. Otherwise,
put a +1/+1 counter on this creature, then put
the card back on top or into your graveyard.)

Whenever you reveal the top card of your library, if it's a land, you may put it onto the battlefield tapped.
