Trigon

Bestow {w} (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.) (The creature you enchant must be a Galactic Starship)
Enchanted creature has "Whenever this creature destroys another creature, put 1 white Galactic Starship onto the battlefield with a converted
mana cost of 4 or lower".
If the enchanted creature would be destroyed,
you can destroy this card instead.
