{t}:You may draw cards until you draw a
non-land, multi-colored permanent.(put all other
cards on the bottom of your library.) Without revealing the card, target opponent guesses a
color in the card's color identity. If guessed right,
put the card in your hand; if guessed wrong, put
the card directly into play and repeat the process.
