Want to Step Into My Mirror?

Exile target creature you control and create a token
that's a copy of that creature. That token is a demon
in addition to its other types & gets a +1/+1 counter.
It also has Indestructible and Hexproof until end of
turn. When this token leaves play, put the copied
creature from exile into your grave & Draw 3 cards.

Put in the game to arouse suspicion of Ms. Emily, I
couldn't have guessed Bender would just walk into her
mirror, throwing out my original plan & changing my
game complete
