Functional reprint cards serve the exact same function as the card they resemble, except they differ in name or name and subtype. This usually has little effect on the game, hence their consideration as a kind of reprint. Functional reprints do not often emulate powerful cards, as they effectively allow some constructed formats access to more than four copies of the same card. Functional reprints are often used to give a new block- or set-themed flavor to a card that plays an important role in defining a particular color.
A functional reprint must have the same power and toughness if it is a creature, but may differ in creature type. The mana cost must be same for colored and colorless mana.
