Transformation

Transformation is a slang term used by Magic R&D to describe the following effect: "~ is a (color) (card type) with base power and toughness P/T." This mechanic is primary in blue.

Transformation can be temporary, through a one-shot spell or ability that lasts for the turn, or more permanent, usually through an Aura. It overwrites the base power and toughness of the creature. This ability used to be in both blue and white, but R&D decided to focus it in blue. Green has started to gain some use, but the general difference is that blue usually uses it as a shrinking effect like removal, whereas green uses it to pump creatures in a way that's hard to compound. The list below assumes the affected creature will lose all abilities, unless noted.
