Gaea's Adjuration

If you're the Knig, sacrifice a creature: search
your library for a basic land card, shuffle your library, and put it on the battlefield tapped and it doesn't untap at your next untap step.
If you're not the King, search your library for a basic land card, put it into your hand, then shuffle your library. At the beginning of your next main phase, you must discard a creature
card. If you can't, discard a card.
