I've been taking a closer look at this metagame and feel like there's a lot of possibilities that can be used for a lot of Pokémon. One that stood out for me the most was Scizor, and I think others had the same thoughts too.
Scizor (Klinklang) @ Scizorite
Ability: Plus
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Gear Grind
- Shift Gear
- Facade / Substitute
- Wild Charge
I had a few feelings that this set might have been used before, but whatever. Scizor loses out on some Technician boosts like Bug Bite, or just any moves under 60 BP. No Bug-type moves at all, either. (with the exception of Signal Beam but that's a special move, while Scizor is mainly physical) Klinklang is not able to utilize a physical moveset to the best of it's abilities except for it's signature moves - Shift Gear and Gear Grind. These moves make Scizor a monster if not killed by any Fire-type Pokémon, and can easily take out one or two Pokémon, if not more.
Substiture or Facade, depending on how you want to play, and Wild Charge to kill any Water-types that might wall you off. Or just, anything that does't resist Electric. Scizor might (and will) have trouble against Physical walls, given that it won't get the chance to set up. Which, if it does, it might get a chance to still take them out. Luckily, Scizor is able to mega-evolve, meaning that it loses it's useless inherited ability Plus in return for Technician again (which Gear Grind benefits heavily from combined with a STAB.) It's also possible for you to invest more into Speed , which can make it outspeed other Pokémon which might be able to kill Scizor before Scizor can kil them despite any boosts.
A huge check for Scizor is Suicune, since Scald can easily burn it and cause a serious shutdown for it. A good core would be someone with Water Absorb, but I am still undecided as to who would fit that role good.
EDIT: After a short time of messing around with possible donors and users I've come up with something that might back up Scizor pretty well. Victini seemed to have the right stats for a Fire-type user (in my opinion, it has decent all-around stats and can do something), and thus I used it for the back-up.
Victini (Maractus) @ Leftovers
Ability: Water Absorb
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Safeguard
- Drain Punch
- Knock Off
- Petal Blizzard / Poison Jab
Also being a physical attacker, Victini's purpose is to be a decent 'check' to Suicune (nowhere being near the perfect check for Suicune, though). It can set up Safeguard rather quickly (I specifically invested in Speed so it can outspeed some more Pokémon), not die to Earth Power from Suicune (it usually inhs from Quagsire), and to be able to either hit super-effectively with Petal Blizzard or hit something else with it's coverage Knock Off for 1.5x boost if the enemy has an item (which they always do; 99% of the time.), hitting heavy even if it does resist, and hitting even harder if it's just neutral. In general, Victini takes care of quite a few Pokémon with it's good coverage from Maractus' movepool.
Disclaimer: This being one of my first self-made sets I cannot guarantee the quality of these sets to be good. There might be a lot of flaws in them, or even something that could make them completely unplayable (well, they could be playable, only not be viable.).
