Curse of Echoes

When the triggered ability resolves, it creates a copy of that spell for each other player. The active player creates their copy and may choose new targets first (if that player isn’t the enchanted player), then each other player (except the enchanted player) creates their copy and may choose new targets in turn order. The last player who creates their copy controls the copy that will resolve first.

All the copies are created on the stack, so none of them are cast. Abilities that trigger when a player casts a spell won’t trigger. The copies will then resolve as normal, after players get a chance to cast spells and activate abilities.

If the original spell has an X whose value was determined as it was cast, each copy has the same value of X.
