Soul Seizer // Ghastly Haunting
Capturador de Alma // Assombração Horripilante
Capturaalmas // Acecho espantoso
Creature — Spirit // Enchantment — Aura
Enchant creature You control enchanted creature.
You choose the target for Soul Seizer’s triggered ability when that ability triggers and goes on the stack. You choose whether or not to transform it when that ability resolves. If the creature is an illegal target by that time, the ability doesn’t resolve and none of its effects happen. You can’t have Soul Seizer transform.
If Soul Seizer has any +1/+1 counters on it when it transforms, they remain on Ghastly Haunting. They won’t affect the power or toughness of the enchanted creature, however.
