Karn, the Great Creator (JP Alternate Art) #1

Activated abilities of artifacts your opponents control can’t be activated. [+1]: Until your next turn, up to one target noncreature artifact becomes an artifact creature with power and toughness equal to its converted mana cost. [-2]: You may choose an artifact card you own from outside the game or in exile, reveal that card, and put it into your hand. Alternate Art version only available in Japanese.
