Except that Audino, Vikavolt and Rampardos aren't in the Viability Rankings.Trick Room is heavly incomplete.
In trick room setters, it dont have Audino; in TR abusers it dont have Vikavolt, rampardos and magearna.
Audino: With acess to TR, Wish, Knock Off and Healing Wish. While she may look like a weakened Cresselia, it dont stack weakness with Bronzong or Exxecute, making the team less vulnerable to Bug, dark and expecialy ghost. And also has regenerator, so she will live a lot. (Isnt in the mega form because it looses the Regenerator ability.)
Vikavolt: Sp.Atack of 145, 43 Speed, good offensive typing and have Volt Switch: In the last turn dealing a lot of damage and bringing the TR setter. Could be better?
Rampardos: 252+ Atk Choice Band Rampardos Head Smash vs. 248 HP / 252+ Def Eviolite Chansey: 637-751 (90.6 - 106.8%) -- 43.8% chance to OHKO
165 attack and head smash. And the fact it can use a Choise Band because you dont want speed, so choise scarf would be idiot, this dude can destroy A LOT.
Magearna: Lets say, Vikavolt dosnt killd when using the Volt Switch, and you used Magearna. Magearna gets 1 free turn, of the dude switching - I wouldnt stay there to increase its SpAttack. Being able to set TR and use it well its amazing. And 65 speed is a little hard to under-speed in Ou.
Neither are Mega Houndoom, Mega Sceptile, Diggersby, Xurkitree, Slowking, Jellicent, non-Mega Aerodactyl, Klefki, Tentacruel, Zygarde-10%, Feraligatr, Alolan Exeggutor (this one should be removed imo), Ludicolo, or Torkoal, but they're still on the compendium. I wouldn't say the compendium is as strictly tied to the VR as analyses are.Except that Audino, Vikavolt and Rampardos aren't in the Viability Rankings.
I think you should add Infernape to the thread. Even though it's not used very much in the meta, it's able to do quite a few thinks in the meta.
It has access to many useful moves. Also has Fire / Fighting STAB, which is pretty good. Though Infernape isn't as strong as he once was back in DPP.
Infernape can be used as a Choice Scarfer. With a base speed stat of 108, it's able to out speed the whole meta unboosted. And it's able to outspeed a +2 max speed timid Magearna and revenge kill it with a Flare Blitz.
252 Atk Infernape Flare Blitz vs. 0 HP / 0 Def Magearna: 300-354 (99.6 - 117.6%) -- 93.8% chance to OHKO
Infernape can also be used as a suicide lead to get up rocks.
It also has three formers of priority
1.) Fake Out- which would be used on a suicide Lead set.
2.) Mach punch- For a physical set or a physical based set.
3.) Vacuum Wave- For a special set or a special based set.
Also Infernape can be used as a set-up sweeper in both physical and special conditions. It has access to Swords Dance and Calm Mind. Being able to boost it's 104 based stats.
Infernape is able to use U-Turn, which allows it to be an offensive pivot.
1. Dugtrio usually runs Pursuit on SPL Stall afaikMaybe add Mega Camerupt to Stealth Rock, its quite a decent user tbh because of the number of swithces it forces. Also I'd add Hoopa Confinded to Nasty Plot users, its kind of a metagame trend but it is very good against stall because it is a Ghost-type and therefore can't get trapped by Duggy.
