Are battlefields chosen before or after turn order is determined in Riftbound matches?

Ruling: In all games of a match, battlefields are chosen before turn order is declared.

Sequence:

• Choose legends
• Choose champions
• Choose battlefields (simultaneously blind)
• Battlefields are revealed
• Turn order is determined
• Draw 4 cards
• Mulligan

Nuances:

• In game 1, both players choose battlefields blind to turn order
• In subsequent games, the player who lost the previous game knows they will choose turn order, so they can select their battlefield with their intended turn order choice in mind, while their opponent can only guess
• After battlefields are revealed but before finalizing turn order, the player choosing turn order can factor in the opponent's battlefield choice
