Resolving copies of permanent spells become tokens as they enter the battlefield. These tokens are not considered "created" when this happens.

A copy is created even if the spell or ability that caused the delayed triggered ability to trigger has been countered by the time that delayed triggered ability resolves. The copy resolves before the original spell.

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

The copy is created on the stack, so it's not "cast" or "activated." Creating the copy won't cause abilities that trigger when a player casts a spell or activates an ability to trigger.

If the spell or ability that's copied is modal (that is, it says "Choose one —" or the like), the copy will have the same mode or modes. You can't choose different ones.

The controller of a copy can't choose to pay any alternative or additional costs for the copy. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy.
