Flying, deathtouch
When Zyym, Mesmeric Lord enters the battlefield, target opponent chooses an order for the cards in their hand, then reveals them one by one until you say stop. That player then discards the most recently revealed card.
While resolving Zyym’s triggered ability, the target opponent can’t rush through revealing their cards. After each is revealed, they must wait for you to choose to continue or stop.
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.
