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.

If the spell or ability has damage divided as it was cast or activated, the division can't be changed (although the targets receiving that damage still can). The same is true of spells and abilities that distribute counters.

Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keyword abilities are activated abilities and will have a colon in their reminder text.

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.
