Hello everyone! After now two weeks of making teams for UUberspl and getting to play some test games and reviewing the replays I can find post Dragceus ban i want to give my thoughts on some things, specifically Arceus as a concept. Arc-less being poor building is already a pretty common take for SV UUbers, and while I understand some of the reasoning for it I want to highlight a few different forms here and talk about some of their basic potential. I intend on revisiting this after UUberspl is done so I can go more in depth into specific team styles without accidentally leaking what I've been building, but felt it still might be useful to touch on this while the tour is ongoing. I understand that I'm relatively new to the tier and hence people might disagree with these takes but I still feel like this is worth sharing.
First up, the Big Three main arc forms I believe to be the most reliable in the format:
Next, 3 forms i have less to say about but I believe round out the main set of Viable Arceus forms.
Arceus Fighting
Arceus Fighting will almost always have some small niche due to its access to STAB Body Press, allowing it to much more effectively start getting setup with sets like Cosmic Power, but is also able to wreak its own offensive havoc due to a reliable special fighting stab, only truly needing shadow ball to patch up the hole that fighting has (just note that it still struggles with ever present Tera Fairy and Arc Poison). That being said, the oppourtunity cost of running Arceus Fighting is huge, especially when it has a lot of notable weaknesses like Fairy and Psychic and nothing to speak of in terms of resistances except Dark, when in all likelihood you will be wanting to Tera out of Fighting anyways. It has cheese potential, but that's the most you can probably expect from it. If Giratina Origin does rise as expected, this probably gets a lot stronger.
Overall, I truly do believe that most, if not all teams should be running some form of Arceus and hope that this post for now helps people get some more ideas for how they could build with, well quite literally God. I intend on posting more collected thoughts about the major players in the tier post UUberspl (and the anticipated Gira-O ban), because this tier has been super fun to build for and play so far and I would really like to see some larger development happening in the upcoming months, as I think this tier has serious potential going forwards.
First up, the Big Three main arc forms I believe to be the most reliable in the format:
Arceus Steel
Touching on this one first as besides grass this is the only one to appear on any sample. Steel is an incredibly strong type, I don't think there is any way you can properly deny that, and despite the plethora of strong fightings and grounds in this tier Steelceus still manages to be incredibly strong in its own right. Offensively, I feel it can be pretty comfortable running mono stab on either side of the spectrum, either with DD iron head sets (though this struggles more into Alomomola) or CM judgement. Its ability to pretty much freely add whatever support move it likes, being Taunt, Will-O, Twave, etc. on top of being able to abuse tera to an incredible degree lets it be a pretty consistent player when it comes to helping teams face down threats such as Chien Pao, Opposing Arceus forms, and frail attackers while also threatening many common pokemon on bulky structures like Alo and defensive Gira-O.
Arceus Poison
Arceus Poison may seem out of left field with the powerful grounds in the format, but rest assured that the merits of this mon across a variety of team styles can arguably rival Steelceus in terms of versatility and overall viability. Poison is a heavily underrated defensive typing when it comes to resisting important types in this tier like Fairy, and Fighting, while still notably being neutral to both of Chien-Pao's STABs. Poisonceus has already established itself in SV uubers as a prime offensive threat with its SD/DD sets, and here I do not believe that changes, and you have the added benefit of greatly increased defensive potential due to the added move pool with excellent tools such as defog, toxic, and the same support moves you could see Arceus Steel running, with the benefits of a different defensive typing that can similarly abuse tera. Overall it has an edge offensively over Steelceus, but still has versatility to help it keep up on the defensive side on builds that can account for its weaknesses.
Arceus Flying
The last of the definitive "big three" Arc forms, Arc Flying is an absolute offensive BEAST on the sheer merit of its Calm Mind sets alone, despite the ubiquitous nature of Chien-Pao in the current state of the tier Flyceus is able to pretty effortlessly threaten almost every single mon in the tier, and having an important defensive niche of being immune to ground, vital when Lando T and Groudon are as good as they are. Its mediocre defensive profile in other aspects limits it a bit in terms of what you can run it on, but when it gets going its incredibly hard to stop. Tera types like Fairy to help limit phasing from Giratina, Steel to resist Ice, or even Poison to become immune to toxic damage and completely sit on Pokemon like Pheromosa let this pokemon stay on the field even longer while dishing out devastating blows (of wind). It may be one dimensional, but its one dimension doesn't stop it from being incredibly effective in its role.
Next, 3 forms i have less to say about but I believe round out the main set of Viable Arceus forms.
Arceus Electric
Arc electric faces a problem similar to Arc Flying, but trades its offensive prowess for almost no meaningful defensive niche. Its STAB paired with Ice Beam will allow it to beat a lot of teams, and DD sets to have a lot of options, but it will require a team that can meaningfully make up for the fact that your Arceus will be largely incapable of taking the hits you need it to take to really get you off the ground. Its good for sure, but much more high risk with a somewhat high reward, which can be very dangerous in an offensive metagame such as this.
Arceus Grass
In my opinion, Arceus Grass is best used as a subsitute for Arceus Poison on very ground weak teams that are able to make up for its weakness to Ice. It is much more able to set up in the face of the grounds that make up the tier staples, and also have the bonus of being able to potentially tear through some Grounds and Bulky Waters, as well as maybe have better defensive matchups on certain team styles. I think the overall defensive downsides of this form are super notable though, and thus should be considered in teambuilding.
Arceus Fighting

Overall, I truly do believe that most, if not all teams should be running some form of Arceus and hope that this post for now helps people get some more ideas for how they could build with, well quite literally God. I intend on posting more collected thoughts about the major players in the tier post UUberspl (and the anticipated Gira-O ban), because this tier has been super fun to build for and play so far and I would really like to see some larger development happening in the upcoming months, as I think this tier has serious potential going forwards.
