Text-changing effect
Template:Navigation CR Certain cards in Magic have effects that can change the text of other cards and are referred to as "text-changing effects" or, informally, as "hacks". Cards with such effects may themselves be referred to as "text-changing effects" but are more commonly referred to as "hacks", a term that has been recognized by at least 5th Edition, by the Glossary of the Official Strategy Guide (5th Edition). Text-changing effects are considered exclusively within blue magic according to the historic and current understanding of the Color Pie, and all cards with a text-changing effect have been blue to date.
Text-changing effects replace each instance of a characteristic with another of the same genus (e.g., color) or type (e.g., basic land subtype, creature subtype).
