Well, I was going to post a priority user, but it's not necessary anymore, I see. Many suggestions are great, so I'm going to give my opinions, before suggesting something new.
Breloom is brilliant, carries Spore, scares out Terrakion and Kyurem and hits hard basically anything. The only concern I have is that it cannot set up SD safely on nothing, since it's OHKOd by, respectively, Psychic from Meloetta, HP Ice from Thundurus, Ice Beam from Kyurem and CC from Terrakion (Metagross threatens to 2HKO with any move not named Pursuit, and since you don't OHKO with +2 Mach Punch you must Spore it before attempting SD). This means you must rely on prediction to set up your SD, while the Scizor set posted is much better at gathering boosts. However, Breloom retains key advantages in more immediate power available, Spore and a resistance to Water - which seems extremely valuable if they pick Choice Scarf Politoed as their last pick (althoug it still takes over 70% from it, and with LO recoil it can mean an OHKO regardless).
Scizor is again a wonderful suggestion. Both Bulky SD and Band have their own advantages.
Band is perfect to scout, dealing over 40% to Metagross and Thundurus with U-Turn (so the Steel-resists are worn down quickly), has plenty of power readily available, and completes the infamous, archetypical VoltTurn core with Scarf Rotom-W. However, the fact that they can exploit a Choice locked Bullet Punch in many ways (Metagross, Thundurus gets a "free" switch-in, and an eventual Choice Scarf Politoed can do the same, and threaten to OHKO with Hydro Pump) can be a letdown. Also, if we want to pick a set-up sweeper, we would have only one slot left, so we would be hard pressed to find something that isn't ruined too hard by Terrakion, has decent type synergy with our team and performs good against their team. THis is not too much of a concern, but still something to be considered.
Bulky SD from alexwolf is very interesting, and probably one of my favorite entry so far. It just needs a bit of damage on the Steel resists, and can easily dismantle their team with +2 Bullet Punches. Roost means easy set-up on Kyurem, so I won't dismiss it easily; however, U-Turn is very useful in my opinion to weaken common switch ins and for general scouting. I once ran a SD | Roost | BP | U-Turn set that performed quite well, I'm not sure it's appropriate here since it means you have to switch out after a SD if Metagross is still up (although it would be a free switch in for Rotom, so not that bad anyway), but it can be an idea nonetheless.
Mienshao is quite underwhelming. Can take out Thundurus, of course, but it's outspeed and eaten for breakfast by Terrakion. It also fails to OHKO Metagross, which can be extremely dangerous since it takes like 65% average from Bullet Punch. It also has basically zero opportunities to switch in, since anything can OHKO him with the appropriate move. It's not bad, but in my opinion we're just better to get a strong priority or something that cannot be taken out so easily.
Haxorus is basically in the same boat of Mienshao, being OHKOd by the whole Team 1 (Meloetta OHKOs 75% of the times with Psychic after SR). It's also slower, thus being unable to outspeed Thundurus, which is another big letdown. If it gets a DD it destroys Team 2, but it cannot achieve it, so it's a kinda moot point in my opinion.
I'm confused about the Forretress suggestion. ShakeItUp said that spinning is helpful for Kyurem/Thundurus (so I guess it would suggest Forretress for Team 1) but also to counter Terrakion (that would hint at Forretress being on Team 2), so I'm not really sure if he/she did some mistake or if it's just me not getting it correctly... Okay, my fault. Still, Team 2 already have a SR user (you could add Spikes instead, for example), and Forretress doesn't really cover our FIghting weakness: LO Terrakion almost 2HKOs with CC after SR, so if Forretress took some residual damage, it's gone.
Right now, Scizor or Breloom are the best looking suggestion overall; I'm really unsure about what it's best for Team 2 between CB Scizor or SD Loom/Scizor, and I will probably support one of those. However, I had an idea that keeps coming out, and I would really like feedback on that since it seems really good, so I'm going to suggest it anyway.
Landorus-T @ Life Orb
Trait: Intimidate
EVs: 252 Atk / 4 Def / 252 Spe
Nature: Naughty (+Atk / -SpD) (Adamant is an option, Naughty gives 100% chance to KO Gliscor)
- Rock Polish
- Earthquake
- Stone Edge
- Hidden Power Ice (/Fly for Virizion?)
Landorus-T brings to our team the Fighting resist we badly needed; not only, but it can basically sweep Team 1 clean without any problem. Come in while Terrakion CCs / X-Scissor Celebi / Set up SR, or after Metagross killed something with any attack not named Meteor Mash, and set up Rock Polish. Then the fun starts:
Earthquake vs 0/0 Meloetta: 313-370 (91.78 - 108.5%) -- guaranteed OHKO after Stealth Rock
Stone Edge vs 0/4 Thundurus-T: 450-530 (150.5 - 177.25%) -- guaranteed OHKO
Earthquake vs 252/4 Metagross: 404-476 (110.98 - 130.76%) -- guaranteed OHKO
Stone Edge vs 52/0 Kyurem: 370-436 (91.58 - 107.92%) -- guaranteed OHKO after Stealth Rock
Earthquake vs 4/0 Terrakion: 554-654 (170.98 - 201.85%) -- guaranteed OHKO
As you can see, it just needs SR onto the field to destroy Team 1 right now. It also outspeed any Scarfed pokemon up to 120 base speed after a Rock Polish (Scarf Tornadus-T trolls him by one point, but noone uses it anyway), so unless they pick Scarf Jolteon or something, the only thing it fears is Ice/Water type priority attacks.
I'm probably still leaning towards a priority user, but I think my Lando-T can still have its own merits. Maybe a Scizor or Breloom / Lando-T combination can be good, giving us solid priority and good sweeping pontential. If your feedback is in that sense, I will just repost the set the next stage and vote for a priority user right now.
