1 Tesung vs [8 HJAD vs 9 Scythe.] - I think if the HJAD Scythe. series displayed anything its that neither was quite ready to be top 12 of an official tournament, you can't be bringing illegal mons or just randomly leaving in the middle of battles at this stage in a tournament. Tesung will win this series easily, but I'd like to see scythe. v tesung in RU so I'm hoping scythe pulls through.
2 Mazar vs 7 Teal6 - should be pretty decent, but I think teal6 is just a more consistent player (RU Ubers v Doubles UU NU)
3 Kingler12345 vs 6 Kushalos - both friends, and the luckiest 2 players alive, my heart says kingler but my mind says kush (LC Ubers v NU UU, comes down to RU (assuming kingler sits doubles, I don't want to watch kingler v kush in doubles o_o))
4 Bouffalant vs 12 qsns - qsns has really impressed me, but bouff is a friend, and didn't sit qsns in ubers which is objectively his worst tier. Additionally, I just don't want to read the inevitable shit post by doubles players that follow a qsns win. (NU Ubers UU v RU LC, but Bouff is more likely to take RU than qsns is to take any of the other three imo).
Would be satisfied with tesung / teal / bouff / kingler / kush overall winner (what a bold prediction xD). GL to the remaining competitors :)!
