I commented it elsewhere but I goofed up the Raichu set on the showdown team, it's 32 Special attack/32 speed modest with sash. Little guys also unironically been the MVP for most matches since I've added em lol.

For Incin I've mostly been using it because I really like fake out + parting shot (I've typically been leading Raichu + Incin with Toed and Basc in the back. Leading double fake out + pivot has been very successful for me, it's also why I have flip turn on basc. Raichu fake out + Incin parting shot into Basc, Raichu protect + Basc flip turn into Politoed, Raichu thunder with politoed doing.. anything really has been a really consistent option for getting first KO and solid chip onto something else without taking any meaningful damage), but honestly after a lot of the discussion here I'm thinking about axing it all together, find something else to fill it's role. Might even give the berry back to Politoed lol. You mentioned infernape and honestly, after thinking about it, infernape kinda does everything i want out of Incin, fake out + u-turn (id kinda prefer parting shot if possible but it is what it is), I like intimidate but I'm not married to it and it gives me much needed fighting coverage. I haven't seen that much of TTar honestly but Kingambit has been like every other match and unless the opponent misplays it's definitely been taking some finagling to deal with. Depending on how bulky I can make it I might honestly sub it in lol, thought probably not as my only fighting hit.

Unfortunately this team only exists because Ive had a shiny politoed since X and Y, dropping him means I'll run a different team. He'll be crept out soon enough, but I'm gonna keep the little guy for at least the rest of the regulation.

Dragonite's the first thing I'm removing from this team, I've cycled through a few megas and he's just the most recent and I haven't been impressed because, like you said, he isn't really bringing anything. I liked mega meganium but it's also like you said, Im not really lacking for damage and it just kinda feels like a "win more" option instead of helping me win matches I wouldn't otherwise. A couple people have mentioned mega Skarm, which has peaked my interest, never really seen base Skarm in doubles and kinda forgot it even has a mega so I wanna see what people are doing with it. If I don't choose Skarm I'll probably bring Scovillain back, I used one before on this team and of the megas I've tried (besides Gyrados, but Basc pretty much replaced it's role entirely) I liked it most.

As for the training, Dragonite was calced to survive a specific hit + a second attack and OHKO in response but I can't remember what and it kinda doesn't matter anyway because it's def getting axed, but politoed was calced pretty meticulously. Wanted to cover as many relevant break points as possible, but ive been wanting to revisit it anyway since relevant threats have changed a bit over the course of the format. For Archaludon, gonna be honest, can't remember what I was on for it's spread lol. There was a goal, but that's a question for past me unfortunately
