@ DD Salamence
While it is true that it has potential against team 2, it is hard checked by Scizor, meaning it can't do as much work as a last pick would be expected. Furthermore, it is SR weak and will be with 75% when coming in as team 1 has no spinner, is slower than Terrakion and Garchomp, and can't OHKO anything in team 2 that it outspeeds other than Scizor, meaning that team 2 can play around it not so difficult. For example if it attempts to set-up on Rotom-W and Rotom-W goes for Volt Switch, then Scizor comes in and revenge kills with BP, and the same goes for Zapdos. Blastoise can either use Roar or Scald in order to bring it to OHKO range from Scizor's BP. I know that the Pokemon that is against Mence will be weakened a lot if not OHKOed by Mence if it stays in and attacks, but the point is that Mence won't have succeded in removing Scizor from the game, and will die after being locked into Outrage (it needs to lock itself into Outrage to do any damage to any of the Pokemon it outspeeds other than Scizor) from Scizor. So, overall, while Mence is not a bad pick, it's not a good one either.
@Bulky LO Volcarona
This is very risky. It has the potential to outright sweep team 2 or do absolutely nothing. If team 1 manages to keep SR off the field long enough for Volcarona to find a switch-in opoortunity, then team 1 wins (Blastoise can take 1 hit from +1 Rona, but this means that we lose our spinner and Rona can still come back later, while our Zapdos gets fucked by Lando). However, should team 2 manage to get up SR fast enough, then Volcarona will hardly do anything. At 50% health Volcarona cannot setup against any of Terrakion (CC OHKOes), Rotom0W (Hydro Pump), Zapdos (Volt Switch + Scizor's priority), Garchomp (both STABs), Blastoise (Roar), and Scizor (both priority moves 2HKO after SR, assuming we don't get unlucky with Flame Body), so unless it is played really godamn well it won't manage to set-up, and even if it does, it will kill one Pokemon at most before getting revenge killed by Scizor. For this reason (unreliability), i don't like Volcarona.
@ LO Starmie
While it is true that Starmie outspeeds and threatens a lot of stuff on team 2, it is also true that team 2 has two really good checks to it. Starmie is forced to predict correctly everytime Rotom-W and Zapdos come in (especially Zapdos, which can only be 2HKOed by Ice Beam 44% of the time from full health), otherwise it will just handle the momentum to team 2, which will start their annoying Volt-turn games. Also Starmie really struggles to find switch-in chances which limits its ability to deal damage against team 2. It can't come in against Terrakion and Terrakion won't be killing anything any time soon against team 1, it can't come in against the 2 electric-types, it can't come into Scizor unless it kills something first, it can't come into Garchomp unless it uses SR, leaving Blastoise as the only Pokemon it can comfortably switch into. We could give Starmie Analytic, which would make it impossible for team 2 to switch into (Psyshock + coverage move 2HKOes everything on team 2, assuming Psyshock is boosted by Analytic), but this would mean that Starmie will have a harder time switching into the only Pokemon it could before, Blastoise. And if Starmie gets statused by Blastoise it will only be a matter of time for Starmie to get into Scizor's Quick Attack killing range (2 or 3 turns). But it is true that 'till Starmie gets taken out it can seriously weaken team 2, and for this reason i think it's a good pick, provided you give it Analytic.
So for now my support goes for LO Starmie, provided you give it Analytic.
A Pokemon i would like to see discussed is Raikou. The SubCM Raikou can get a ton of set-up chances and butcher team 2 with the right game plan, while the LO set can become a vicious attacker akin to Starmie, but much harder to revenge kill and wall and easier to bring in. The LO set also needs zero prediction, as the only Pokemon that can switch into Thunderbolt is outsped and OHKOed by HP Ice.
EDIT: Also about Starmie. Ice Beam is not really needed if we go with Analytic, as Zapdos is 2HKOed by Psyshock on the switch, and Garchomp can be forced to use Outrage and get killed by Kyu-B after. This means that we can easily give Starmie Rapid Spin to make Kyu-B's life easier.
