Owlin Spiralmancer

If a spell with a converge ability is copied, no mana was spent to cast the copy, so the number of colors of mana spent to cast the spell will be zero. The number of colors spent to cast the original spell is not copied.

The copy will have the same targets as the spell it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).

If you cast your first spell with {X} in its mana cost during a turn before Owlin Spiralmancer is on the battlefield, casting another spell with {X} in its mana cost later in the turn won't cause its last ability to trigger.

If the spell that's copied has an X whose value was determined as it was cast, the copy has the same value of X.

A resolving copy of a permanent spell becomes a token. That token isn't "created" and won't interact with abilities that care about tokens being created.

The copy is created on the stack, so it's not "cast." Abilities that trigger when a player casts a spell won't trigger.
