I didn't work very hard on spreads, just 252/252 for most of them and ripped off a smogon set for milo.
Mega Audino is probably a cmonBruh mon, but with 4 pretty strong TR attackers, I figured it wouldn't matter whether or not the setters were passive, so long as I could ensure TR would be effective and keep going up when I wanted it to. This team tries to take advantage of the fact that a lot of people's best answers to trick room are either strong offensive leads, have intimidate, or hold a berry in order to survive a little longer. This team however is probably easily exploited by psyspam, it probably wants/needs to be refined in order to deal with it more easily (the obvious answer would just be Tapu Fini > Milotic and a better mega, but I feel like that would really fuck up Hariyama's Guts more than Audino's Healer, and fini relying on berry recovery and having an additional weakness and less power is a drawback from Milotic, and nothing can replace the meme power of using Mega Audino).
This is a pretty straightforward set, Ice Beam helps deal with zygarde and stuff, Protect keeps me from getting bodied, Recover keeps me alive. I generally don't like psychic trick room setters since they are weak to knock off and u-turn, and often have shitty recovery options, and this sorta isn't like that.
Another straightforward set, but you have to be careful not to put Mega Audino next to this unless you really have to, as it can remove the guts boost with healer. The solution would probably just be to heal pulse Hariyama on the switch-in, and if the boost is lost, fake out+trick room/switch out audino to stall out the nerfed turn. As far as why it's here, it's super strong and is auto-statused to deal with z trick room and amoonguss, and gets fake out ofc.
week 20 mon. Also deals with Intimidate in an interesting way, while its great coverage lets it take on the world under trick room. It's a great mon tbh, tier 0 worthy.
Lucifer Sam. It's strong, can spam Intimidate, has Fake Out. All around good pokemon.
Another good check for Incineroar, this has a z move just because none of the mons on the team had a z move yet. This is here instead of Tapu Fini because it's stronger and slightly bulkier on the special side, and because the terrain would fuck up Hariyama's Guts, AND because it has better recovery than just a berry.
0 SpA Audino-Mega Incinerate vs. 36 HP / 112 SpD Kartana: 204-240 (76.1 - 89.5%) -- guaranteed 2HKO - kinda neat, Kartana can't set up sub while under trick room and loses its berry.
Audino's mega form isn't necessarily much better to be in than its non-mega form, as Regenerator and a lack of a steel/poison weakness helps it take hits from things that would otherwise KO the mega form, while also not interfering with Hariyama's Guts. Mega-evolving is something you'd want to do if you were about to take a heavy hit and needed it to live. Heal Pulse provides recovery for Hariyama and Lurantis and keeps Incineroar and Milotic healthy. Magic Coat is there to help deal with sleep and taunt, though this one is a little bit filler as I have fake out support and healer. With Incinerate, Audino has something it can do against the overly-fruitful 50% berry meta game while also acting as a strong way to deal with roar Suicune, which would otherwise just prevent trick room being set for fucking forever by not dying when it's supposed to and roaring the setters.
On the other hand...
252 SpA Deoxys-Attack Shattered Psyche (200 BP) vs. 252 HP / 4 SpD Eviolite Porygon2 in Psychic Terrain: 435-513 (116.3 - 137.1%) -- guaranteed OHKO
252 SpA Deoxys-Attack Shattered Psyche (200 BP) vs. 252 HP / 252+ SpD Audino-Mega in Psychic Terrain: 382-451 (93.1 - 110%) -- 56.3% chance to OHKO
:/ This is depressing. Working around this would probably require some prediction and potential sacrifice, but since Deoxys-Attack is a piece of paper and Lele doesn't like taking hits from any of my mons, I think this can be played well into a win.
