Expedition Leader

{t}, Exert Expedition Leader: Target creature you control explores. (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 that creature, then put the card back or put it into your graveyard. An exerted creature won't untap during your next untap step.)
"I've been all over this world. And unlike Goblins, I actually remember those places!"
