Carmelia Sharpsong

You may look at the top card of any opponent's
library. You may play those cards by paying
mana as though it were mana of any color to cast
those spells.
Disguise Expert — {1}{u}: Until end of turn,
Carmelia Sharpsong is a copy of a target creature,
except its not legendary and if its destroyed while it
is a copy of another card, return it to the battlefield
as Carmelia Sharpsong instead.
