Under my alt of Requiem952, I have managed to place 28th on the ladder for Fortemons. Here's the team I used.
Kartana @ furycutter
Ability: Beast Boost
EVs: 252 HP / 4 SpD / 252 Spe
Timid Nature
IVs: 19 Atk
- Swords Dance
- Sacred Sword
- Night Slash
- Leaf Blade
I saw people talking about Fury Cutter being potentially broken, and while I haven't noticed its effect doubling attacks even when a single one isn't spammed, I never really needed to. Sit this thing down in front of a non-fire, non-fighting physical mon, have it SD once or twice, then proceed to watch the fireworks as it absolutely demolishes the opposing team. It's IVs and nature are to ensure that Beast Boost ends up increasing Speed, turning it into a nigh-unstoppable sweeper when given the chance to score a kill. The only way to handle it after a Beast Boost is a priority Fighting or Fire move, both of which are shut down hard by the next 'mon on the roster.
Tapu Lele @ Choice Scarf
Ability: Psychic Surge
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Psychic
- Psyshock
- Moonblast
- Focus Blast
Anti Prio. Absolutely a must, when everyone and their mother runs at least one threat to my team that happens to throw around priority like nobody's business. Scarf Lele is a remarkably potent revenge-killer, and with Psychic Terrain can do some pretty serious damage to anything that isn't a dedicated special wall or otherwise immune.
Scizor (M) @ uturn
Ability: Technician
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Bullet Punch
- Bug Bite
- Superpower
- Roost
A powerful 'mon with the ability to switch out first OR last? Sign me the hell up. Being able to choose when Scizor switches out by choosing either Bug Bite or BP makes this thing a scary good pivot. Roost can also be replaced with Defog, albeit at the cost of survivability. Superpower destroys Traprans and dents Celes that try to switch in, or to take advantage if Rotom's Discharge-Switch scores a paralysis against the former.
Rotom-Heat @ voltswitch
Ability: Levitate
EVs: 248 HP / 252 Def / 8 SpA
Bold Nature
IVs: 0 Atk
- Pain Split
- Defog
- Discharge
- Overheat
Primarily acting as support and an answer to those physical threats that Kartana can't sit on, Heatom acts as a secondary pivot as well as my answer to hazards. Pain Split has proven to be a surprisingly effective tool at keeping it alive,
Porygon-Z @ triattack/secretpower
Ability: Adaptability
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunderbolt
- Ice Beam
- Tri Attack
- Substitute
I haven't yet actually tried using Tri Attack as Porygon-Z's item, but I am wondering if that would give all its moves a 20% chance of proccing Burn/Freeze/Para and give Tri Attack two shots at that 20%. Regardless, Secret Power happens to work really well here too, since that 30% paralysis really gives me a fun time. It's not necessarily as 'necessary' as the others, but I find that Pory-Z is a good mixup option, and BoltBeam makes it even more... if not unpredictable, then 'concerning'.
Goodra @ absorb
Ability: Sap Sipper
EVs: 248 HP / 252 SpA / 8 SpD
Modest Nature
IVs: 0 Atk
- Ice Beam
- Flamethrower
- Thunderbolt
- Draco Meteor
I really have to say, there is something beautiful in sending this thing out and watching it clean house. The only problem that this monster faces in this meta are offensive fairy-types (read: Lele), Protect Traprans, and most physical 'mons. Granted, I have multiple answers to each in Timidtana and Heatom, so that's more or less mitigated. However, being able to fire off powerful attacks with that clean 350 SpA, and drain half the damage done, means that you basically need to send out a physical 'mon or Lele to keep Goodra from continuing its rampage. Combine that with a grass immunity in Sap Sipper (a middle finger to Celesteelas and the occasional Bulu), and you cannot sleep on this thing. It might not have the same way of handling Flame Charge mons like Blacephalon, but as far as I'm aware Charge-cephalon either needs a crit or Shadow Ball's 20% SpD drop to get rid of this thing before Goodra can get rid of it in return. Fear the slime dragon. Rawr.
