Blackreef Cove

When you planeswalk to Blackreef Cove, or at
the beginning of your upkeep, choose target card in your graveyard at random. If it is a nonland card, cast it without paying its mana cost. If it is
a land card, put it on to the battlefield.
{c}: You may switch your graveyard and library, then shuffle your library. If you do not, put the top ten cards of your library into your graveyard.
