What is the precise order of setup steps in Riftbound, specifically what information is revealed before determining who goes first or second?

Ruling: All Legends, Champions, and Battlefields are revealed before determining first player and turn order. Players do not draw their opening hands until after the first player is determined.

Sequence:

1. Reveal Legends
2. Reveal your Chosen Champions
3. Privately randomize/choose battleground (method depends on game type)
4. Reveal battlegrounds simultaneously
5. Shuffle Main and Rune Deck
6. Determine first player and turn order (FFA4/2v2: remove battlefield of first player)
7. Draw 4 and mulligan (up to two cards to the bottom of your deck, redraw that many)

Nuances:

• In FFA4/2v2 formats, the battlefield of the first player is removed after determining turn order
