Whenever you cast an instant or sorcery spell from your hand, open an Attraction.
{X}, {T}: Exile target instant or sorcery card with mana value X from your graveyard and choose an Attraction you control that doesn't have a midway counter on it. Put a midway counter on it. For as long as that Attraction is on the battlefield, whenever you visit it, copy the exiled card. You may cast the copy without paying its mana cost.
Myra’s activated ability creates a delayed triggered ability that will trigger whenever you visit the chosen Attraction. This ability will continue to trigger as long as the Attraction is on the battlefield and the exiled card remains exiled, even if Myra leaves the battlefield, loses her abilities, or changes controllers. It will also continue to trigger if the Attraction somehow loses the midway counter.

Myra’s activated ability targets only the instant or sorcery card in your graveyard. It doesn’t target the Attraction. You choose the Attraction as the ability is resolving.
