In 1v1 Riftbound, do you randomly pick your battlefield or can you choose what you want?

Ruling: In a best-of-1 (single duel), the battlefield is random. In a best-of-3 match, you pick your battlefield.

Sequence:

• Battlefields are revealed before drawing cards and mulligans
• In best-of-3, the battlefield is discarded going into game 2 and cannot be reused in the current match

Nuances:

• The distinction between single duel and match format determines whether battlefields are random or chosen
