Addendum
MTG Mechanic
Addendum is a new ability word. Ability words don't have any inherent rules meaning, so addendum is more of a label than anything else. It's found (mostly) on instants that have additional or alternative effects if you cast the spell during your main phase. So, if you're willing to give up a little flexibility, you are rewarded with extra potency.
