Bilbo's Map

{2}, Sacrifice Bilbo's Map: Search your library for a basic land card, reveal it, and put it into your hand. Then shuffle your library.
If you control a Hobbit, explore. (Reveal the top card of your library. Put that card into your hand if it's a land card. Otherwise, put a +1/+1 counter on target Hobbit creature, then put the card back or put it into your graveyard.)
