X (UST-137) is a legendary Human Spy creature from the Unstable set. While X can be put into an opponent’s hand and then be cast or have its abilities activated by its owner, the opponent whose hand contains it plays with their hand revealed and cannot cast X or use its abilities. X’s activated abilities let you return it to an opponent’s hand and allow you to play a land or cast a spell from the hand X is in for no mana cost when you pay {3}{U}{B}.
