Kruppe, Mischief Maker

Whenever you attack a player with a creature you
don't own, draw a card and create a Treasure token.
{4}{r}: Gain control of target creature until end of
turn. Untap that creature. It gains haste until end
of turn. Activate this ability only any time you could
cast a sorcery.

"None of you have ever seen Kruppe dance! And
dance he can, with breathtaking artistry and
grace—nay! He glides like an unbroken egg on a
greased skillet.
