Mimzy, Party Crasher

Mimzy can't block and can't be sacrificed.
At the beginning of each opponent's upkeep, you
may have target player gain control of Mimzy until
end of turn. If you do, she gains shroud until end of turn.
Creatures you opponents control attack each combat
if able and attack you if able.

"Sorry about the mess, but I'm sure the little bug can take care of it for ya!"
