Cinderella

At the beginning of combat on your turn, put a
beauty counter on another creature you control
and choose one:
• That creature is unblockable until end of turn.
• That creature's base power and toughness
become equal to the base power and toughness
of another creature you control with a beauty
counter on it.
"You are now a heroine who can't fail at love."
