You and the other team leader have to schedule the date and time for the scrim, as you normally would. However, when picking maps both of you have to cross one of the following maps:
- Twin Peaks Extreme
- Hidden Valley
If a team wins 2 on US and 1 on EU, they win (or vise versa). If the teams are tied (2-2) then you will need to add up the scores of all the matches you played.
If you need help, contact a league manager to help sort out this scrim.
