Apollo, Pyro-Advokist

Whenever you cast an instant or sorcery spell,
choose target creature and flip a coin. If heads,
gain control of that creature if its converted
mana cost is equal to or less than the cast spell.
Otherwise, Apollo, Pyro-Advokist deals damage
equal to that spell's converted mana cost to that
creature.
