Tournament organization.

Due to the availability of Duel mode, you can first organize a multiplayer tournament, and then the winners with their armies will compete for victory in duel mode.

What does "their armies" mean? The ones they manage to gather on the multiplayer map, or how? And how can this be balanced? Maybe for the duel, the jury can come up with an army in advance for each castle? And the factions that the players will play will be distributed by lot? And all this can be organized according to the Olympic system - first a round with qualifying groups - then a knockout round?
