Reveal the top X plus one cards of your library and separate them into two piles. An opponent chooses one of those piles. Put that pile into your hand and the other into your graveyard.
X can be 0, and piles can be empty. If X is 0, you’ll reveal one card and one pile will be empty. Your opponent may choose the empty pile to put into your hand.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
