Just in case anyone isn't convinced Groudon himself isn't a problem, i took an in-depth look at his Tinted Lens set. The Results are what i expected. The set's counters are 100% reliant on Primordial Sea and Fur Coat. There are also very few mons that can check his Tinted Set as well. The Following calcs are based on this set:
Groudon-Primal @ Choice Scarf
Ability: Tinted Lens
EVs: 252 Atk / 4 SpA / 252 Spe
Naughty Nature
- V-create
- Thousand Arrows
- U-turn
- Blue Flare/Trick
Lets Start off against the most logical Primal Don check/counter: the strongest Water Type, Primal Kyogre. A full defensive PH set can barely check Don. Scarf Sets are reliant on speed tie or Don not being Jolly. Or the Scarf set could be Primordial Sea.
252+ Atk Tinted Lens Primal Groudon V-create vs. 252 HP / 252+ Def Primal Kyogre: 318-376 (78.7 - 93%) -- guaranteed 2HKO.
This were things get dicey. What else "checks" Tinted Don. You can also use Mega Swampert, though its viability in BH isn't exactly the highest. Protean Mega Mewtwo sets won't work either:
-2 252+ Atk Primal Groudon V-create vs. 0 HP / 4 Def Mega Mewtwo X: 410-486 (116.1 - 137.6%) -- guaranteed OHKO King's Shield Calc
252+ Atk Primal Groudon V-create vs. 0 HP / 4 Def Mega Mewtwo X: 411-484 (116.4 - 137.1%) -- guaranteed OHKO.
252 Atk Protean Mega Mewtwo X Land's Wrath vs. 0 HP / 0 Def Primal Groudon: 260-308 (76.2 - 90.3%) -- guaranteed 2HKO
The only way Mega Mewtwo X wins this is if its Scarf as well, and Protean Scarf isn't optimal. MMx would also have to carry Crabhammer. Mega Mewtwo Y has the same issues as X, though it does ohko with Earth Power, and doesn't need a Water Move.
Rayquaza is the only Fake Speed user with a shot to OHKO Don. The rest can't do it, and if you don't get that kill you are solidly OHKO:
252+ Atk Life Orb Aerilate Mega Rayquaza Fake Out vs. 0 HP / 0 Def Primal Groudon: 103-122 (30.2 - 35.7%) -- 35.3% chance to 3HKO
252+ Atk Life Orb Aerilate Mega Rayquaza Extreme Speed vs. 0 HP / 0 Def Primal Groudon: 207-243 (60.7 - 71.2%) -- guaranteed 2HKO
252+ Atk Tinted Lens Primal Groudon V-create vs. 0 HP / 4- Def Mega Rayquaza: 456-538 (129.9 - 153.2%) -- guaranteed OHKO
What about other threats like Arceus, Palkia, Ho-Oh, Xerneas,, and Yveltal?
252+ Atk Primal Groudon V-create vs. 252 HP / 4 Def Arceus: 352-415 (79.2 - 93.4%) -- guaranteed 2HKO
252+ SpA Life Orb Arceus Boomburst vs. 0 HP / 0 SpD Primal Groudon: 337-398 (98.8 - 116.7%) -- 93.8% chance to OHKO
252+ Atk Primal Groudon Land's Wrath vs. 4 HP / 0 Def Palkia: 207-244 (64.2 - 75.7%) -- guaranteed 2HKO
252+ Atk Primal Groudon V-create vs. 252 HP / 252+ Def Yveltal: 307-363 (67.3 - 79.6%) -- guaranteed 2HKO
252+ SpA Yveltal Oblivion Wing vs. 0 HP / 0 SpD Primal Groudon: 159-187 (46.6 - 54.8%) -- 64.5% chance to 2HKO
And Slowbro:
0 SpA Tinted Lens Primal Groudon Blue Flare vs. 252 HP / 0 SpD Mega Slowbro: 240-282 (60.9 - 71.5%) -- guaranteed 2HKO
Summery:
Checks:
Palkia
Kyogre
Arceus
Counters: (the following need Primordial Sea or Fur Coat to counter)
Giratina
Mega Slowbro (only Primordial Sea)
Mega Audino
Lugia
Of the "Counters" only Giratina and Mega Slowbro can beat Tinted Lens sets and Mold Breaker sets. Its checks all need free switch ins, they lose otherwise. If this set isn't too Powerful for the metagame, i'm not sure what is. This isn't even Don abusing anything more then its STABS+ one ability and it threatens almost the entire metagame and forces teams to run Fur Coat/Primordial Sea. I stand by my previous stance. Primal-Groudon needs to be banned, not nerfed by Species Clause or a restriction that would go against the nature of Hackmons. It needs an outright ban!
