Batching

Not to be confused with Batch.

Batching is R&D slang term used for the action of taking various (preexisting) game components and then connecting them into a larger group with a new word. Mark Rosewater sees batching as a design tool with interesting design space.

Black border

• Historic was the first example of batching. It collectively refers to artifacts, anything with the legendary supertype, and Sagas. The keyword refers to historic largely in the context of cast spells or cards off the battlefield, though three refer to historic permanents.
• Party is a mechanic that batches Cleric, Rogue, Warrior, and Wizard. The keyword refers to creatures controlled, and all paper designs use it to return a numerical value - one digital design refers to it like a type.
• Modified is a batching term formally introduced in Kamigawa: Neon Dynasty. It refers to creatures that are equipped, enchanted, or have counters on them.

Acorn

• Decorated cards include premiums, promos and cards with alternate art or alternate card frames. This batching term was found on the Acorn card Topdeck the Halls.

Unreleased

• Mystical was considered for Throne of Eldraine. It would batch artifacts, enchantments, and Faeries.
• Six cards over six different sets batch together Serpents, Octopuses, Leviathans and Krakens as an undefined "sea creature" collective. It is treated like a singular tribal type due to lack of card density.
