2009-05-01 : Abilities that trigger when a spell is cast (such as this ability or cascade) won’t trigger when you create a copy this way.

2009-05-01 : If a modal spell is copied, the copy will have the same mode as the original.

2009-05-01 : 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. The new targets must be legal.

2009-05-01 : This ability triggers only once for each multicolored instant or sorcery spell you cast. You can’t use a single Cloven Casting to copy the same spell twice.

2009-05-01 : You can copy the spell that caused Cloven Casting’s ability to trigger even if it’s been countered by the time that ability resolves.
