Vexed Mirror

Whenever a non-token creature you control enters the battlefield or dies, you may pay {2}{r}. If you do, you may create a token that
is a copy of that creature, except it's power
and toughness are X/Y, where X is equal to
that creature's toughness and Y is equal to
that creature's power. It gains haste. Exile
it at the end of your turn.
