Considering THIS HAPPENEDI think the most broken thing right now is Araquanid. 100/120/172 bulk and Regenerator makes it bulkier than Toxapex both on the physical and special sides, with the same number of weaknesses (only 3) to boot. Unlike Toxapex, it has enough offense (90 Atk) to run Assault Vest, and AV with the previously mentioned bulk makes it a better special (and physical, obviously) wall than Chansey. Fortunately, it has a Rock weakness, so at least whoever runs Araquanid will be forced to run hazard control to fully utilize Regenerator.
Now, with a buffed Attack stat and with Water Bubble being Huge Power for Water moves, it can also be a scary wallbreaker, hitting harder with Liquidation than Crawdaunt with its Adaptability Crabhammer. Unlike Crawdaunt, it has the bulk to be able to set up. Araquanid also has Spider Web to trap a passive foe, set up on them and atempt a sweep. Many possibilities. Again, fortunately, Araquanid doesn't get Aqua Jet and it is quite slow, so it's more of a wallbreaker than a sweeper. Unless you're using a Trick Room team, that is...
The vanilla Araquanid set, suicide lead, also gets a buff, with Spikes and Drizzle to further support its teammates. Granted, there's nothing broken about Drizzle Araquanid, it's just that more sets means more unpredictability and it'll be hard to predict and counterplay Regenerator/Water Bubble sets already.

Araquanid restored a little HP using its Leftovers!
Araquanid's taunt wore off!
Yeah, I'd agree. Went a bit too far with his design, probably would drop some of that spdef and def and put it into spatk for a mixed attacker. Probably also not have Swords Dance, Bulk Up is fine alone. Hariyama also is ridiculous alongside Rampardos, pure bulk and pure power is terrifying.
Also a few errors were popping up such as U-Turn and Spectral with Golisopod and Rock Head on Rampardos.
