ok, I've just read these rules:
Rules:
All matches are 'Best of 5'.
Players can agree on which scheme to play first, the loser gets the next pick, then alternate until someone reaches 3 wins first.
If players can't agree on first pick, play 'Comet Dodging' to decide who gets first pick, then alternate.
Map choice and style is decided by the player who picked the scheme, opponent cannot refuse the pickers map choice.
and it was Stoner's pick. and not even the streamer noticed. but anyweh
