Easiest Way to Boost
Set up a custom 4 player non-ranked match with these settings:
3 Private Slots
Invite 3 friends into the game and begin. Have consistent teams throughout with both leaders coordinating on the rock, paper, scissors game. Alternate wins by letting the clock run out. DO NOT play any cards because the clock will pause while placing cards. DO NOT do match games because all games in the match count as one win.
Took me 3 hours to get exactly 40 wins so plan on it taking at least 7-8 hours to get 100 wins for everyone in the party.
