Really? I could be wrong but it seems to me you need to go 7 wins (and Max 1 loss) with all 3 buffs to get 9-0 regardless of when you lose.Only have to go 6-1 with all 3 active which should be super easy. (7-1 if the first round is a loss)
Buff 1: Start with a win
Buff 2: First win counts as 2
Buff 3: First loss is ignored
Win 1st game: 3
Win 2nd: 4
Win 3rd: 5
Win 4th: 6
Win 5th: 7
Win 6th: 8
Win 7th: 9
