How would the NDAG format accept Grass-Dragon Contrary Serperior +Leaf Storm+Draco Meteor?

This is not an open ended question. Or the start of a list of hypothetical questions regarding modified Pokemon types. I am asking only this question, preferably to someone who understands the National Dex formats a lot more than I do.

If Serperior gained the Dragon type, and was able to get Draco Meteor, on top of it’s high Sp.Atk and it’s access to Leaf Storm,on topof it’s Contrary Hidden Ability, what tier would it rise to in the AG format. Losing its weakness to fire is not that big of a deal as Fire is not relatively a common type in the competitive scene. What new checks would it obtain, and what would be the new Pokemon to counter it.

After reading the rules again this question is ok to be asked.

I’m not sure if this breaks the rules or not, but I’ll go ahead and answer.

It wouldn’t be that great.

Let’s take a look at it’s matchup against some of NatDex AG’s top threats.(All calculations give Serperior the Dragon typing, so it gets STAB)Calyrex-ShadowAn incredibly potent sweeper in the metagame. It’s speed is higher than Serperior’s, and it’s special attack….252 SpA Life Orb Calyrex-Shadow Astral Barrage vs. 0 HP / 0 SpD Serperior: 320-376 (109.9 - 129.2%) –guaranteed OHKOPretty high.252 SpA Choice Specs Serperior Draco Meteor vs. 0 HP / 4 SpD Calyrex-Shadow: 220-259 (64.5 - 75.9%) – guaranteed 2HKOAnd here’s a display of how Serperior’s SpA…isn’t great. Even with specs and STAB.

YveltalAnother huge threat in the metagame. Runs Specially Defensive, Physically Offensive, or Specially Offensive sets. Isn’t quite as fast as Serperior….252 SpA Choice Specs Serperior Draco Meteor vs. 0 HP / 0- SpD Yveltal: 250-295 (63.6 - 75%) – guaranteed 2HKO

252 SpA Choice Specs Serperior Draco Meteor vs. 252 HP / 252+ SpD Yveltal: 160-190 (35 - 41.6%) – guaranteed 3HKO

But can take a hit regardless. But can it hit back hard enough?

252+ SpA Life Orb Yveltal Oblivion Wing vs. 0 HP / 0 SpD Serperior: 398-468 (136.7 - 160.8%) – guaranteed OHKO

Offensive Yveltal can.

0 Atk Dark Aura Yveltal Knock Off (97.5 BP) vs. 0 HP / 0 Def Serperior: 184-217 (63.2 - 74.5%) – guaranteed 2HKO

SpD doesn’t quite OHKO, but does a large amount of damage, and gets rid of your item. It also hasU-Turnwhich does ~50% and lets you switch out to something likeDittoorCalyrex-Shadowthat can outspeed it and take it out.

Zacian-CrownedOutspeeds, immune to Dragon, resistant to Grass, OHKOs with behemoth blade. Enough said.

Arceus-GroundGroundceus’s physical attacking set can OHKO if it has Jolly, as it runs Ice Beam as coverage despite being mostly physical for Zygarde. Physically Defensive also runs ice beam, but serperior is faster. It should OHKO with a specs super effective STAB Leaf Storm…right?

252 SpA Choice Specs Serperior Leaf Storm vs. 252 HP / 0 SpD Arceus-Ground: 378-446 (85.1 - 100.4%) – 6.3% chance to OHKO

Not always. Usually not, in fact. As for Ice Beam, that OHKOs.

Honorable mentions:Ditto:takes advantage of boosts, destroys with Draco MeteorFairyceus:takes a hit, destroys with Judgement.Mega Rayquaza:is OHKOd by Draco Meteor if Serperior holds Specs or a Life Orb, but outspeeds and OHKOs if the Rayquaza is Jolly or holds a Choice Scarf.Eternatus:Offensive sets outspeed and annihilate, defensive sets can take a Draco Meteor and strike back with an OHKO.

(Do note that many of the above calculations give Serperior Choice Specs to show it’s max firepower, but this leaves it vulnerable to fairy types or one of the many things that resists grass, and if you don’t hold specs, it’s firepower is even more depressing)

Serperior also doesn’t have much coverage at all. It’s only notable coverage move is Hidden Power (which is weaker than STABs in nearly ever case)

In conclusion,Serperior lacks the bulk, firepower, coverage, and sometimes even the speed to compete with AG’s top Pokémon.
