SoulWind vs Manaphy - soulwind is obviously solid, but his prep help is situm who famously kept bringing his shitass galvantula webs and kept running into set up zygarde. while soulwind by himself is also capable of building a solid team, the problem is manaphy will prolly bring some psywave bronzong or something else slightly unconventional that might catch soulwind off guard and def not be part of his prep. so as long as mana+reje don't slack off first day on the job, i think they're slightly more favored.
Icemaster vs byronthewellwell - i haven't seen byron ss, so idk how is own builds are doing and if he has settled in or not, but rabbit did get many shoutouts in upl for being the only mukker not whining about mons and being a good help in ss so his assistance should be good. edge to icemaster for prep only as both have shown many times to be great level-headed players
M Dragon vs Exiline - i think the game will go like this: one player will be in a great spot (not directly winning), then the other player will get a lucky break and win. mdragon has pomman to help with prep and exiline has fellow frenchman staxi+degenerate cousin fatfighter2, as long as the latter trio of stupidity doesn't go overkill on prep i think exi will win cos more experience+great form in the past months
Fc vs 64 squares - neither of them have a mainer on the team to help prep, so fc will prolly have aid from billy while there's no telling who'll really help 64. predicting fc cos i don't have much to gauge 64's ss from so fc is favored cos of more experience in the long bulk vs bulk struggles of ss ubers
Poek vs TrueNora - i realise this is my first prediction for the mainer to lose. gasp. with tony's help i don't think poek will run into any matchup issues unless nora brings some garbage that loses to a very common mon that poek luckily doesn't have on his team. nora has luna to keep his evil desires in check, but there's a catch - luna loves woeful weavile. playing wise, poek is obv more experienced and well balanced while nora has shone tendencies of not calcing and rushing things in the game, so i pick poek to win based on that.
