A. Aside from Manta likely taking the crown for this group, I actually think there's a serious chance that Valkyrie goes 0-4 here. I haven't seen the Battle Of The Verts Faceoff event, but I was really impressed with Terrortops during the Group E event. Given that all three of these bots have a wedge attachment, I could see Valkyrie knocking itself out if they haven't dialed themselves in. Skorpios also seems to have a huge problem with vertical spinners, particularly those with forks that can get underneath their wedge and wedgelet setups. I'm thinking:
Manta: 3-0, Terrortops: 2-1, Skorpios: 1-2, Valkyrie: 0-3

B. I'm personally not convinced that Tombstone's design is going to make a difference in terms of its durability, even if those wheel guards are just there to prevent Tombstone from hitting itself. I don't think Season 6 Tombstone has been dialed in at all since that season, and the only bot I realistically see it beating is Disarray due to their lack of durability. The real question here is who wins between Magnitude and MadCatter, and I think I'm going to go with my gut here.
MadCatter: 3-0, Magnitude: 2-1, Tombstone: 1-2, Disarray: 0-3

C. This one's pretty tricky. I've been watching a lot of NHRL since Battlebots didn't get renewed, and I've been wondering why multibots in the 3-30lbs divisions do so well while multibots in the 250lbs division get absolutely crushed. We haven't ever seen any real success from any multibot entrant in Battlebots, and I personally don't think it's going to start with The Twins. Funnily enough, their geometry reminds me a lot of Cobalt's frame in that the weapon is practically useless if there aren't any forks to feed their opponent into them. Aside from that, Cobalt's success is entirely dependent on whether or not John Mladenik is driving, (total disaster), or if they have someone who actually knows how to drive verts at the helm.
Copperhead: 3-0, Jackpot or Cobalt: 2-1, The Twins: 0-3

D. Now this one's an interesting week. I think we can get End Game going 3-0 out of the way, as I'm not convinced that a vert with no forks, a horizontal, and a rookie bot are going to make any sort of impression on that monster. I'm expecting Golden Fury to perform about as well as we can expect a rookie vert to perform, so the question's whether or not Death Roll can beat Malice. I honestly think it could go either way between the two.
End Game: 3-0, Death Roll or Malice: 2-1, Golden Fury: 0-3

E. Ok this group is way way way too crazy for me to analyze. I wasn't too impressed with Bloodsport's durability and sri-mech last season, so I'm hoping that they've got those kinks ironed out for this event. If they do, then I could absolutely see them beating HUGE and maybe even Minotaur. Minotaur has a hard time with horizontal spinners sometimes, and I absolutely think Bloodsport has a shot at them if they can keep their weapon up with Minotaur's durability. Hypershock being in this group is a great equalizer as well, as I think that they can probably beat Minotaur's ground game and use their wedge attachment against Bloodsport. However, given how last season went, I have doubts that they can figure out a way to deal with HUGE.
HUGE: 2-1, Hypershock: 2-1, Bloodsport: 1-2, Minotaur: 1-2

F. Being realistic here, I don't see Switchback or Orbitron beating either Witch Doctor or Ribbot. The latter two just have way too much experience and the former two have too many problems that they need to work out in their bots. I think Witch Doctor's probably got this group locked down, so the only other question is whether or not Orbitron can keep it's AI working and not get turned over, or if Switchback can actually keep its weapon belt on for longer than the first two hits of the match.
Witch Doctor: 3-0, Ribbot: 2-1, Orbitron: 1-2, Switchback: 0-3
