904.13. Archenemy Commander Option
Subrules
As an alternative option, players may play a Commander game (see rule 903, “Commander”) using the Archenemy rules. The normal rules for Commander apply, as modified by the Archenemy rules, with the following exceptions.
Poison counters are not shared. If the archenemy has ten or more poison counters, they lose the game. If any individual member of the opposing team has ten or more poison counters, they lose the game. (This is a state-based action. See rule 704.)
The archenemy’s scheme deck must contain at least ten cards, and each card must have a different English name.
