Heartbreaker, Iron Man Suit

Bestow {3}{r} (If you cast this card for its bestow cost,
it's an Aura spell with enchant creature. It becomes a creature again if it's not attached to a creature.)
Flying, haste
Enchanted creature gets +1/+1 and has flying
and first strike. If enchanted creature would be destroyed, you may remove all damage from it
and destroy Heartbreaker, Iron Man Suit instead.
