What is the correct sequence for game setup in Riftbound, particularly regarding when leaders/champions are revealed, when battlefields are chosen, and when turn order is determined?

Ruling: The game setup sequence has a specific order where champions and legends are revealed first, then battlefields are chosen and revealed, then turn order is determined, and finally players draw and mulligan.

Sequence:

• Reveal Champion and Legend
• Choose and Reveal Battlefields (method depends on type of play)
• Determine Turn Order and First Player
• Draw and mulligan

Nuances:

• Items should be revealed simultaneously, but the choice must be made before either player reveals
• You cannot change your chosen champion based on opponent's legends in Game 1
• Turn order is always chosen after battlefields are revealed (this applies to all games including games 2 and 3)
• Sideboard rules and whether chosen champion/legend can be swapped between games are to be determined in upcoming tournament rules
