Here’s my thought process
Hatterene (lead): get trick room set up, plus has decent spread with dazzling gleam. Psychic is also good for sneaseler
Pelipper (lead): weather ball is good for incin. Hurricane also does well against sneaseler. Ice beam for more anti-salamence and anti rilaboom. Wide guard also hard walls hyper voice because that’s all mega salamence clicks these days aside from tailwind
Clawitzer (backup): backup salamence counter if one of them goes down. Dark pulse also good for Basculegion. Plus life orb boosted, rain boosted, mega launcher boosted STAB water pulse is an absolute nuke for anything neutral, and it also serves as backup incin counter
Archeladon (backup) haha electro shot go brrrrrrrrrrrrrrrrrrr. Flash cannon also does well for floette
Turn 1: set up trick room as always. Originally was gonna go for hurricane to put rilaboom in a bad spot, but thought about going for ice beam to pressure mega salamence. But eventually settled on wide guard so that way if salamence did survive ice beam, wide guard would keep Hatterene safe. Fortunately they went for tailwind, so that means no matter what is thrown at hatterene, she’ll survive cuz of sash. Hatterene luckily survived with 19 HP, thus allowing TR to get up safely
Turn 2: hatterene in major danger of grassy glide, so we protect, and after quickly checking what I had in the back that could switch into a grassy glide next turn, I turn mega salamence into a popsicle. Grassy glide goes into the hatterene which is nice, and since ice beam GOT THE FREEZE, mega salamence couldn’t do anything
Turn 3: i still know grassy glide is still incoming, so I swap into archeladon to take anything that is thrown at me nicely. Hurricane into rilaboom since mega salamence is practically used up anyways. They swap mega salamence into sneaseler, which keeps me safe for now, and rilaboom is put in a bad spot after going grassy glide into archeladon, giving him a stamina boost, and healing archeladon back to full (which doesn’t really matter)
Turn 4: electro shot go brrrrrrrrrrrrr, and hurricane into sneaseler to take care of rilaboom, and possibly take out sneaseler. Hurricane gets the confuse, and once rilaboom is down, SNEASELER HITS ITSELF WITH THE CONFUSION, taking sneaseler down.
And with that, they rage quit. I gave my thought process, so plz give me any flaws I may have in my thought process. I also showcased movesets and stats for everyone on my team, so feel free to do with that as you will
