Toxic + Venoshock Scolipede. Also some other silly things like Sand Attack + Confuse Ray Umbreon and Power-Up Punch Greninja (is that a thing?), but mostly Toxic + Venoshock Scolipede.

(L) Lead Smeargle that does nothing but spam Superpower off a powerful 20 Attack stat. I can understand having Superpower on Smeargle given what the rest of the team is, but why actually use it?
(L) Everything besides Smeargle seems to be Contrary Assist Spinda. That really isn't a good gimmick so stop using it
(R) Ambipom. Not to mention, its set seems to be Fake Out/Taunt/Baton Pass/...Fury Swipes? Fury Swipes is still weaker than Return after Skill Link jsyk
(R) Gyarados is running Return. Normal has nice neutral coverage, but most of the time you'd be better off running something that hits something super-effectively instead.

Left seems to have a team composed only of Mightyena/Emolga/Wigglytuff/Durant. Maybe they just really like those Pokémon? (Also, forfeit at the end of the first turn after the opposing Mega-Ray OHKOs Wigglytuff.)

M-Aero sweeps a mono Pikachu-Cosplay team.

Nothing too silly here, except for the fact that Left's Mega-Blaziken is running Brick Break and Acrobatics when HJK and Brave Bird exist, respectively and Right's Shuckle attempts to use Toxic five times in a row against a foe with a substitute (while allowing Scolipede to get set-up unhindered). Okay, yeah, that was pretty silly.
edit: wait I just realized Scolipede is immune to Toxic now it's even sillier

Mono Pikachu-Cosplay has a Raichu on it now, for some reason.

(R) Groudon-Primal spamming Double-Edge until its health is below half, then using Eruption. That makes sense.
(L) Normal Charizard. It's running Fire Blast + Fire Fang, too. c'mon if you want to run two STABs at least do Fire Blast + Flare Blitz
(L) Darmanitan using Fire Fang against Kyogre-Primal. Darmanitan in general in AG, for that matter.
(L) Garchomp spamming Draco Meteor even after its Special Attack is already weakened to the point of unusability.
(R) Kyogre-Primal Hyper Beam. I think Origin Pulse would have KO'd but w/e
(L) Haxorus using Earthquake against M-Rayquaza. Same thing I said about Darmanitan.
