When do I reveal my Legend and Champion?

According to RiftJudge FAQ #7835 and #2282, the setup process for a game of Riftbound requires that you reveal your Legend and Champion simultaneously at the very beginning of the game, before any shuffling, determining the first player, or drawing cards.

The correct sequence is:

1. Reveal Legend/Champion: Place your Champion Legend and Chosen Champion face-down in their designated zones, then flip them over simultaneously to reveal them to your opponent.
2. Place Battlefield: Place your battlefield(s).
3. Determine Starting Player: Determine who goes first.
4. Reveal Battlefield: Simultaneously reveal the battlefield(s).
5. Draw Cards: Proceed to draw your opening hand.

Performing these reveals simultaneously prevents players from counter-picking their choices based on what the opponent has selected.
