I can't wait to see how this match goes. I'll try to get my comments and predictions in now before it starts.
Fortunately, there were a lot of things that I think went right with only a handful of things that went wrong. So, since it's easier to name what I think was an error I'll just mention those. I think a big mistake for Team 1 was choosing Lando-I as the first Pokemon. There's nothing wrong with the Pokemon itself, it's just that we prevented ourselves from choosing a Lando-T latter in the project despite the fact that there were many other excellent options to choose from at that time. After that, I want to say Jirachi was a mistake as well. The whole point behind Slowbro was to get something that wouldn't throw free turns in Team 2's face while freeing up the third choice for something offensive. Instead, we picked something that was still pretty weak and easy to exploit and I think it'll serve as an excellent way to take back lost momentum. In spite of these two defensive picks, Team 1 seems quite vulnerable to Scizor and Rotom while Terrakion and Garchomp are still going to make them feel very uncomfortable. (only Rock resist being easily exploited while Garchomp forces a kill on Azelf and lures out Kyu-B/Jirachi to take advantage of) The weaker hazards game I think will hurt Team 1 quite a bit as well. As for Team 2, the big (and probably only) mistake was not having Roar on Zapdos (over HP Ice) as it meant we had a special wall that couldn't handle the special setup sweepers. This opened up a whole that had to be loosely covered and which Team 1 will try to take advantage of with Raikou.
Personally, I think Team 2 is going to win this match. Terrakion and Garchomp are pretty much forcing mechanic play while Zappy+Rotom+Scizor is covering all of Team 1's offensive threats and denying them momentum with their Volt-Turn shenanigans. The only real soft point is Blastoise but even he can Roar out any attempts to setup with Raikou and can even be sacked once he's done his job of keeping SR away. Team 1 is going to have to find as many free turns to bring Raikou in as possible if it wants a shot at victory, however the pivoting to Scizor will really pester it. Fortunately, Volt Switch lets Raikou attempt to wear down Scizor itself (preventing the Bug from mashing the U-Turn button when faced one-on-one) but Quick Attack is still going to tear 37% min away from it's HP which means that, with SR factored in, Raikou is unlikely to survive the second meeting with Scizor. It's going to be tricky prediction based match until the dog goes down but once it does, Team 2 should be alright. Course, I'm pretty biased towards Team 2 and have been this entire project.
