I'm thinking this:
Chaos is an extremely good battler, and odds are he could take it, then again, we've been working on defeating stall teams lately, and I know Chaos uses those most the time, though you can't possibly underestimate him because he also pulls out his own creations on you.
Husk is a new, up and coming battler, when he first started out, he wasn't that great, but now I can see him coming up with his own creations, and getting better at battling, he definately isn't a bad battler, and seems to be able to time things right in battle, I can see him putting up quite a fight before going down.
Kirby is one of the most innovative people I've came across on making up movesets, and new ideas, he comes up with entirely new ways to battle, which is great, the bad thing is, all the people who are left in the tournament know about his Assist team, and I have no doubt they will thrown in a counter incase he uses it.
Even without his Assist team though, Kirby is a great battler, he is awesome at UU battles, if he doesn't win this one, I can see him putting up a humongous fight in the UU-BL tourney you are hosting, if he enters that is.
Which he should.
Luvdisc is a new player, which unfortunately I haven't been able to get to know yet, however, he defeated Gon, which in itself is a feat, as I've battled Gon, and he was quite hard.
I think this fella is a little better than we think.
Jaws is a personal friend, I know him for real, he definately isn't "easy" to beat by any means, we battle each other when we are getting fed up with easy battles, and all our battles are extremely close, and the outcomes are usually 50-50ish, I think our records against each other are exactly the same, he has a fairly well balanced team, though I know it's weakness, however I wil, not exploit it here, as he is a personal friend, I'm hoping he wins :P
SatansLittleHelper isn't really the greatest battler, I've defeated him with ease, and he simply starts insulting me, and barraging me with abuse, he also seems to act tough in front of other people, weird since it's only online, and he has become more of a Smogon person than a PC person, I see him losing to Jason (Jaws) in this round, though you never know what suprises people are going to pull out.
So yeah, I'm going for Jason, not because I think he is the best battler, but because I know him for real.
I know one thing for sure though - Whoever gets chaos next is in for a tough time.
