Rotating format
Rotating format is the name given to a tournament format which only allows cards from a selected number of expansions, which changes over time. Rotating formats are used in Standard and formerly in Extended.
Rotation is based on blocks, rather than individual sets. There are three exceptions however:
- Coldsnap was pegged to Time Spiral block for rotation (however, due to regulation changes in Extended, Coldsnap rotated out earlier than Time Spiral block instead of rotating out together).
- The two mini-blocks Lorwyn and Shadowmoor counted as one block.
- The three sets of Tarkir block block are split into two separated blocks for rotation: Where Khans of Tarkir and Fate Reforged counts as one block, and Dragons of Tarkir(pegged with Magic Origins) counts as another.
Banned lists
A banned list exists for every rotating format (see Block Constructed).
