There’s a chance you’re looking at this set going “Wtf is this guy smoking” and I swear I can answer that. I started out by wanting to build a sun team, but I also wanted a Groudon that could take hits. The first thing I knew was that I would need a Max HP, so 252 HP was entered. Then, I figured I would need some SDef to tank some of those powerful hits from the Uber tier. I went to the calcs and started boosting the SDef until I was happy with the result, 160 provided me with good breathing room and survivability. I knew I would need some Def EVs as well, otherwise powerful physical attackers like Band-Oh and Excadrill would still give me issues. Knowing I wouldn’t need as many Def EVs as SDef EVs, I worked it out the same way. Increasing the Defense until I was happy with the hits Groudon could take. I then dumped the rest in Attack, and slapped an Adamant nature on him. With this spread however, I wasn’t sure what kind of moveset would work well, I originally thought Band, but SteelJackal suggested that with this spread I could easily get away with Double Dancing Groudon. So I adjusted the moveset and went to test. First game he swept the opponent’s team. I was flabbergasted. But I knew that the set was definitely not perfect, as I’m still a n00b, so I asked Sweep what he thought. He said two things, “Always speed creep”, and, “248 HP so you have an odd number for HP”. And so I took 4 Atk EVs and 4 HP EVs and threw them in Speed. After a couple weeks of using the team, I was facing someone with a Latios. I was at +2 and +2, all set to sweep. Latios survived Stone Edge with 0.3%...
So I took 4 Def and put them in Attack. The spread was perfected as much as possible.
Rock Polish and Swords Dance are my stat boosters, and it isn’t too difficult to set them up on most leads. Darkrai can provide issues with Dark Void, but I can normally deal with that just fine. The most trouble I have is against Defensive walls who can afford to switch in on +2 EQ and the next turn phaze me. Hippowdon is an example of this. SDef Giratina-A is 2HKO by +2 EQ as are Kyogre, Mewtwo, Palkia, Espeon, and several other common Uber Pokemon. Stone Edge completes the EdgeQuake combo, and works beauties against the Lati twins, Xatu, Ho-Oh, Tornadus, Landorus, and Shaymin. It gets a OHKO on all of them, except Landorus who takes hefty damage from it (when it hits). Groudon himself doesn’t utilize the sun much, except to assist in his survival. ScarfPalkia under sun gets a 3HKO with Spacial Rend, which hits harder than Hydro Pump (sun). Kyogre locked into Ice Beam (who stupidly stays in) will get a 2HKO if Specs and 3HKO is Scarfed. PsychoKiller Mewtwo gets a 2HKO with Ice Beam. Excadrill under sun falls to Groudon. Under sand Groudon can tank +2 EQ then retaliate in kind with a OHKO. If the opponent is running some gimmick like BalloonExcadrill, then Groudon still has the upper hand (seeing that Groudon being in will almost guarantee that I have weather), but as Excadrill can’t do enough damage without +2 I still take the day with Stone Edge to pop the balloon and then KO with EQ. I could continue talking about Groudon, but I think you get the gist. I’ll continue with the team.
Here are some calcs, gonna link it because I don't wanna jump the character limit.
