Comments

You might wanna add some restricted Legendaries or something. Xerneas alone eats everything but Gengar after Geomancy.

No. Not Xerneas. Everybody knows that Dialga is better just because it isn't a fairy type.

---

Sumwun he meant that Xerneas beats everything here, so he should get a counter, not that he should use it.

---

I actually haven't had a ton of trouble with Xerneas. My Arcanine can survive a Geomancy boosted Dazzling Gleam/Moonblast  and then go on to KO Xerneas with Iron Head, same with Gengar and its Sludge Bomb.

Groudon/Xerneas lead basically wrecks that though, with Earth Power/Precipice Blades KOing Gengar and Arcanine.

-1 252 Atk Primal Groudon Precipice Blades vs. 0 HP / 4 Def Arcanine: 152-182 (92.1 - 110.3%) -- 56.3% chance to OHKO
-1 252+ Atk Primal Groudon Precipice Blades vs. 0 HP / 4 Def Arcanine: 168-200 (101.8 - 121.2%) -- guaranteed OHKO
252+ SpA Primal Groudon Earth Power vs. 0 HP / 0 SpD Assault Vest Arcanine: 152-180 (92.1 - 109%) -- 43.8% chance to OHKO

0 SpA Primal Groudon Earth Power vs. 0 HP / 4 SpD Mega Gengar: 152-180 (112.5 - 133.3%) -- guaranteed OHKO
252 Atk Primal Groudon Precipice Blades vs. 0 HP / 0 Def Mega Gengar: 236-278 (174.8 - 205.9%) -- guaranteed OHKO
-1 252 Atk Primal Groudon Precipice Blades vs. 0 HP / 0 Def Mega Gengar: 156-186 (115.5 - 137.7%) -- guaranteed OHKO

Note how none of the Gengar calcs even have a boosting nature.

Basically I'm seeing a HUGE weakness to most of the "Big Six" (Xerneas, Groudon, Smeargle, Kangaskhan, Talonflame, Salamance), Geomancy especially. You have NO Pokémon with Protect, offering zero protection from Fake Out, Dark Void, Double-Edge spam, Eruption, Precipice Blades/Earth Power, Brave Bird, etc.

My number one suggestion would be to toss Protect on everything, especially Gengar.

Alternatively, you could run RayOgre instead of Greninja / Goodra to get some heavy hitters on your team that can also handle Groudon. Something like Ferrothorn or Mawile would compliment a Kyogre team well with their potent Steel attacks.
