This creature's power and toughness are equal to the number of lands in either player graveyard.
{6}{r/g},{t}: Look at your opponent's top card on their library, if it is a land you may send it to the graveyard. If its is not a land, your opponents may draw it and take 5 damage or they exile the card for 2 of their turns and after that during their next upkeep they may put that card on their hand.
