No perhaps I wasn’t clear, you do not need to play exactly 2 warm-up games. If you both feel confident you know the matchup well, you don’t have to play any! If you both feel you don’t know the matchup at all, or want to explore it in great detail before “officially” starting, you can play 10, 20, 30 games of it!
As long as your partner is game to do so, you need not feel pressure to finish this in the next month or two, you can start official games after 3-4 months of warm-up games if you and your matchup pair so choose. This Series is meant more-so to be a loose organization of interested forum members exploring all the mono matchups together over time, not a race to get super-official matchup results.
