The Duel Commander format (previously 1v1 EDH) is mainly based on the multiplayer Commander rules

​​

 

Compared to multiplayer commander, there are some particularities

• For many years, the starting health points used to be 30 (40 for multiplayer commander). Now each player starts the game with 20 health point as in all classic 1 versus 1 format. The recommended round time is 50 minutes.

• Due to the new change in the health points, there is no “21 commander damages” rule anymore.

• The mulligan used to be different from the one used in sanctioned format (partial mulligan). The scy-mulligan is now the official mulligan.

• Duel Commander has its own banlist.
