Has Ostone been playing still regularly? Even if out of shape I'd say he is the strong favorite of this group.
Match 3 ( supremo Sheik, Shave, 5te1n)
If Shave can avoid getting teamed this should go well for him.
Match 4 ( Enjoi, SyDe, Nightwing, Voxius)
Gotta rep USA here with Eshan but Syde is <3, sorry buddy. If Eshan can manip the others into teaming Syde he can take this however, so this will be a tough battle for Syde. If he can avoid that, he's the clear favorite due to his excellent mechanical skills.
Match 5 ( qwest, Airenikus, M00se, MoonAndino)
Qwest favored but Airen isn't bad. Battle of the manips.
Match 6 ( Junkerzam, Neytpoh, Tukimkim, Gradient)
Oh now this should be interesting. Junker and Neutron should be very familiar with Gradi's style, so this could turn into an interesting 3 way, with Tukim the clear underdog. I think I'd favor Neutron here just a little bit, but Junker definitely has a strong chance.
Match 7 ( Trunkz, Peanut, iOwnedU, Vyvanne
Trunks probably. I haven't played in 1.5 years, just playing for fun.
