Pour repondre directement a ta question,
Baseline : Second list is optional. All lists are subject to
the same point constraints and must be led by warcasters
or warlocks from the same faction. Players cannot include
the same version of a model or unit with FA C in more than
one list.
Divide and Conquer [X]: Each list must be played at least
X times during the tournament. The goal of this variant is to
challenge players to use their lists equally prior to the final
round so that a list decision is available. If this goal is not
achievable based on the expected number of rounds, Divide
and Conquer is not recommended.
