Double target creature's power until end of turn. Flashback {4}{R}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Niche combat trick for aggressive red decks, but the effect is narrow and temporary—most strategies prefer permanent pump or evasion over a one-shot power doubling that requires a second creature already in play.
