K.D. Team Hopper

K.D. Team Hopper enters the battlefield under
the control of an opponent of your choice.
At the beginning of the controller of K.D. Team Hoppers upkeep, that player takes 2 damage
and exiles the top card of their library. The
owner of this card may cast the exiled card until
the end of their next turn and you may spend
mana as though it were mana of any type to cast
that spell.
