Undying Apprentice

Scourge {b/r} (If this creature would leave the battlefield, you may pay its scourge cost. If you do, exile it instead and return it onto the battlefield under your control at the beginning of the next end step.)
You may only return Undying Apprentice to the battlefield form exile as long as you control a creature with power 4 or greater.
"Dying in battle is an honor, returning to fight again is power"
