What is the correct order for game setup actions (determining first player, drawing starting hand, mulligan, selecting battlefield), and how does this change in rounds 2 and 3 of a best-of-3?

Ruling: The setup order is: show Legend and Champion, pick battlefield, determine turn order, draw 4 cards, then mulligan if desired. In subsequent rounds of a best-of-3, skip the Legend/Champion reveal step.

Sequence:

• Show Legend and then Champion
• Pick battlefield
• Determine turn order
• Draw 4 cards
• Mulligan if you want

Nuances:

• In rounds 2 and 3 of a best-of-3, the Legend and Champion reveal step is skipped (they remain the same from round 1)
