since the format of masters is always set, they can just draft before kickoff/stage 1 even ends
for masters 2, they would just draft the matchups like so:
EXAMPLE RANDOM DRAFT:
all seed 1s get byes
match A: amer #2 vs apac #3
match B: china #2 vs amer #3
match C: emea #2 vs china #3
match D: apac #2 vs emea #3
now you can even draft the (0-1) and (1-0) teams
SAMPLE DRAFT FOR (0-1) AND (1-0) POOLS
match E: loser of match A vs loser of match D
match F: loser of match B vs loser of match C
match G: winner of match A vs winner of match B
match H: winner of match C vs winner of match D
THIS CAN BE DONE WITHOUT KNOWING WHAT ANY OF THE TEAMS ARE MEANING THERE WILL BE NO RIGGING
