Mirror Figment

Kicker {u}{x}
Exile target creature you control whose
toughness equals 1. Create a 1/1 blue token
illusion creature.
Instead, if Mirror Figment was kicked, exile
creature whose toughness equals X. Create a 1/1
blue token illusion creature; it enters the battlefield with X +1/+1 counters.
During your next end step, sacrifice this token creature and return exiled creature to the battlefield under your control.
