Meddling

Meddling is a slang term used by Magic R&D to describe the ability that names a spell, after which that spell can't be played as long as the card with the ability is on the battlefield. This ability is named after Meddling Mage from Invasion (Chris Pikula's Invitational card). Originally not a common ability (only two were printed in the pre-Mirrodin era), the design space and acceptable applications widened with time.

The ability is usually found on a creature or enchantment. As this is proactive, it is primary in white. Blue is tertiary, with artifacts having a large share of related abilities.
