Exile target creature. It's on an adventure. When it enters from being on an adventure, it explores. (Its owner may cast it from exile. To have a creature you control 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 the creature, then put the card back or put it into your graveyard.)
