Servus! Before the tour starts I'd like to talk about some staples in the meta and some strategies that have been seen and some that are not used but should be.
First the, in my opinion, top 3 of the metagame. There should be at least two of them on a team. They can fullfil many roles but one thing that they have in common is that they provide at least one thing both offensively and defensively to the playstyle of a team.
Great Tusk is easily the best Pokemon in the tier. In my opinion, every team needs to run it, the only exceptions are Stall, Sand and some teams that refer want to use Ting-Lu as a Ground. Aside from that, you do nothing wrong with this guy. It fullfils the role of a Spinner, progress maker with Knock Off and Stealth Rock, Wallbreaker, Sweeper and Tank. Being Hazard Removal that Gholdengo is scared is scared of is really good, especially since it is faster than Gholdgeno, so mispredicting against it isn't a end all be all. Its Tera is also flexible.
Although the other two here get better use of their Tera, Tusk is still a great Tera Pokemon. Water and Fairy are great defensively, Ice and Fire are great for offensive sets and booster energy variants since they boost Ice Spinner or prevent Will-O-Wisp respectively and Ground is great for boosted Headlong Rush. The other two are probably more volatile and dangerous than Tusk but the fact that Tusk fullfils roles that fit on many teams and the fact that it can solidly check the other two while the reverse isn't true, is what puts in on number 1 for me.
Gholdengo needs no introduction. Its type combo and ability give it great defensive utility and many opportunities to what it wants, which usually is attack or set-up. It has great set versatility and all of its sets are good, even unusual options like Substitute, Dazzling Gleam and Psyshock add more depth into its offensive potential. Its defensive potential is also amazing, with Covert Cloak, Air Balloon, Leftovers and weakness Berries being great options in that slot. Tera is also amazing on it. Fairy, Flying, Water, Ghost, Steel and Fighting are all great types to turn into and help it immensily both offensively and defensively. It fits well on hazard stack teams, offensive teams and bulkier variants with set-up can also fit on slower teams.
Kingambit is probably the only Pokemon here that only has one good set but that set is good. It is generally weaker with G-Max Pokemon being around and them having the extra bulk but its bread and butter of SD, Sucker Punch and Iron Head is really useful in this meta. It mainly fits on offensive teams but it does serve its role well by wallbreaking mid game and cleaning late game. Being a natural check to Gholdengo is a nice thing to be. Kowtow Cleave is probably the best option for it since it has great power and is better against defensive Pokemon that resist Steel. Low Kick is also great against opposing Kingambit specifically. Tera is also really flexible here. Fire, Flying, Ghost, Dark, Fairy and Water are all great fits and it can even reliable run Tera Blast.
Useful Dynamax Pokemon
Now onto this mechanic. I will be honest, a dedicated Gigantamax Pokemon will be better in 99% of games. Dynamax is niche but it can be useful, especially when you play to its strengths, which are setting weather or terrain and raising the user's speed when using Max Air Stream. Thus, some Pokemon can use this when they can afford it and when a Gigantamax does not fit your team.
- Max Hailstorm activates Slush Rush, Max Knuckle boosts Attack and Max Lightning makes Bolt Beak stronger and makes Valiant or Moth better partners.
- Max Geyser activates Swift Swim and it can boost itself with Max Knuckle.
- Max Flare and Max Darkness boost its damage output in some way and the former makes it more flexible on Sun teams, resetting sun in some situations.
- This one cannot hold an item either way, when using Gorilla Tactics. Therefore it has no opportunity cost.
- Max Airstream boosts speed, Max Knucle boosts Attack, Max Lightning boosts Bolt Beak and Max Moves never missing works well with Hustle. Max Rockfall can also be used on Sand Rush variants.
- STAB Max Airstream. While not a strong move anymore is usable Flying STAB and it benefits well from it.
- It can substitute the Sub on its Booster Energy set with Discharge and benefit both from Max Moves and the Quark Drive boost.
- Same as moth, but running Booster on this mon is generally better
- Extra bulk and Max Steelspike and Max Quake both boost its defenses and Max Knuckle boost its attack.
- Same as Gyarados but better since it has a Flying STAB outside of Dynamax.
- Almost any move it runs benefits from being a Max Move. Max Geyser boosting Water moves, Max Flare activating Protosynthesis and boosting Hydro Steam. Max Airstream boosting speed.
Great Gigantamax Pokemon
This list isn't really long, especially since most formes haven't been tested yet but some proofed themselves to be great.
- Does not need to Giga right away and has great moves.
- Same here.
- Great Tusk check and status spreader, useful for Bulky Dragapults and Bulky Gholdengos.
- Max Moves and Hustle work really well together.
- Bulky, hazard stack and generally good moves.
- Good Pokemon already, the extra bulk and potential Light Screen improve its offensive threat.
These Pokemon can also be useful, but they have not been used yet or they have not have had great success yet:
Changed Pokemon
I will only focus on those Pokemon that have had the biggest impact and the ones that are generally good additions on any team.
At first I didn't know what to think of it, but it is the best check to Kingambit we have. The typing and physical bulk offset its lack of reliable recovery, resorting to Drain Punch. It also has great utility with a decently strong Flip Turn and Jet Punch. Palafin honestly needs to be bulky to be good since it it is lackluster with its speed and its bulk is where it is strong.
Annihilape is a good Stealth Rock setter and it is a good check to Great Tusk even. Running enough speed almost always ensures that you check Great Tusk and either recover the health you used or get your own rocks up. Not having set-up is bad and Rage Fist having recoil is even worse so it is significantly worse against bulk and you have to be careful with it since one slip up costs your entire slot.
Iron Bundle loosing Freeze-Dry was a big blow and thus it isn't as threatening as you want it to be. However, it is still fast, strong and good attacks with Surf and Ice Beam and its main strength comes from its utility moves. Encore, Taunt, Destiny Bond, Haze and Defog are all great moves to have. It is overall weaker but it can be great support for offensive teams with the aforementioned moves.
I'm gonna keep these short since most of them aren't super different from vanilla.
Wo-Chien is obviously the most different, with the whole type change. It has become better since it has better typing to check Special Attackers like Gholdengo and Hatterene while it has good match-ups against Kingambit and some Iron Valiant sets. Being weak to Great Tusk's Ground STAB is bad but it was weak to Great Tusk's Fighting STAB, so yeah. Overall, it is good now, just needs more testing.
Chien-Pao is just weaker and slower but other than that it is still solid. It is less likely to pick up KOs thanks to the nerf but that is honestly alright lol. Freeze-Dry is now a solid option for it since it can hit Toxapex and Dondozo for more damage but it is hard to fit.
Ting-Lu is Ting-Lu. It can often run Curse now and with Rest, it can play like Dondozo and reliably set-up against foes like Gholdengo and Dragapult.
Chi-Yu is honestly overrated? Like yes, it is good and not missing Fire Blast is always great but it needs time to get going and it sometimes underperformes but it is still something to think about when building.
I also didn't touch on Slate 3 or 4 Pokemon since their main strengths come from Gigantamaxing or they are new, therefore they need more testing.
Useful/Good Pokemon that need more testing
I mentioned this in my previous post, but I feel like these Pokemon have potential or are good in vanilla OU. Some of them are less viable in this meta though due to a lack of reliable support (i.e. Snow Warning setter for Arctozolt) or better competition (i.e. Great Tusk > Excadrill) but never the less, but they niches:
Good Cores:
+
+
/
- Hazard Stack + Toxic spreading for Hex users.
+
+
- Stonjourner boosts the power of Iron Valiant and Great Tusk, allowing them to break through their checks.
/
/
/
/
+
/

/
- Offensive threats with support moves. Allowing set-up sweepers to clean.
+
+
- Defensive Core that checks a lot of the most relevant threats in the meta
Some Teams I've build:
- Stonjourner + Valiant Offense
- Tatsugiri + Gmax Odor BO
- TR GMax Hatt + Scarf Chi-Yu
- Snow Arcto + Agility Wake
- Specs Hex Ghold + GMax Butterfree
- Bulky SR Ape + CurseLu
- QD Mane + Muscle Gambit
This is my experience in this meta. It is fun to build in and play. I think that Terastallization and Dynamax both provide depth to the meta and there are a lot of unique strategies you can run. I think overall, Gholdengo and Kingambit are still a bit on the stronger side and the Gigantamax formes are not all equal, but this is something that the tour will hopefully help us to solve.
