Ok so I took an originally sun-based team of Groudon, Reshiram, Mewtwo, EK Arceus, Ferrothorn, and Ho-oh, and eventually whittled it down to this. It counters single/dual weather teams quite well, and though it seems slightly counter-intuitive, the combo of Groudon and Kyogre works quite well. After certain checks, for example opposing Kyogre or Palkia are taken out, scarf Reshiram/scarf Kyogre can quickly take down a team with their deadly STAB moves. Team at a glance: Groudon @ Leftovers Trait: Drought EVs: 4 HP / 252 Atk / 252 Spd Adamant Nature (+Atk, -SAtk) - Stealth Rock - Earthquake - Fire Punch - Stone Edge Groudon sets up Stealth Rock rather reliably, and readily takes on common leads such as Forretress and Deoxys-S with Fire Punch and Earthquake, respectively. Max Atk is run to cripple opposing leads, and max Spe is run to suprise the slower dragons such as Dialga. The coverage moves are really there to nail Ho-oh and Ferrothorn, who can cause some of my sweepers a lot of trouble. Nota Bene, if Deoxys-S comes in, I always use Earthquake, because 9 out of 10 times, it always Taunts. Why is that??? Reshiram @ Choice Scarf Trait: Turboblaze EVs: 4 Def / 252 SAtk / 252 Spd Timid Nature (+Spd, -Atk) - Blue Flare - Draco Meteor - Dragon Pulse - Flamethrower The epitome of offense under the sun- really just click Blue Flare or Draco Meteor as the situation demands. The given nature and EVs are the standard for a scarf pokemon. It's an excellent revenge killer, and given that sun is up and my opponent doesn't have Kyogre, which isn't too hard to acheive with some help from Ferrothron, Reshiram can really smash holes into the opposing team. Dragon Pulse and Flamethrower are really just there for consistancy in case you need to take down threatening Pokes at low HP. I'm tempted to run a mix set with Outrage just to deal with Soul Dew Latias. Would that be appropriate? Kyogre @ Leftovers Trait: Drizzle EVs: 252 HP / 4 Def / 252 SDef Calm Nature (+SDef, -Atk) - Scald - Roar - Rest - Sleep Talk To absorb status and tank neutral hits, I found that Kyogre works AMAZINGLY well. Scald is for STAB and Roar is an excellent phazing move to abuse Stealth Rock and Spikes set by Groudon and Ferrothorn. Works well as a counter to lead Darkrai too. Palkia @ Choice Scarf Trait: Pressure EVs: 4 Atk / 252 SAtk / 252 Spd Hasty Nature (+Spd, -Def) - Draco Meteor - Outrage - Fire Blast - Surf Now something to abuse Kyogre's rain! Palkia has the obligitory STAB Draco Meteor and also has Surf, which is easily spammable after some dragons are out of the way. Outrage is to deal with Latias, but is a little on the weak side, and is easily exploited by opposing Ferrothorn due to high defense, Iron Barbs, and access to Leech Seed and Thunder Wave, so it comes down to Outrage vs. Thunder. Fire Blast to use under the sun to deal with Ferrothorn/Forretress. Arceus (Arceus-Ghost) @ Spooky Plate Trait: Multitype EVs: 252 HP / 4 Def / 252 Spd Timid Nature (+Spd, -Atk) - Judgment - Flamethrower - Recover - Will-O-Wisp Powerful attackers with priority such as Extreme Killer Arceus and Rayquaza would be a threat, but they get fucked by Will-O-Wisp, effectively neutering them for the rest of the match. Sayonara. Judgment is the obviously STAB move, while Flamethrower pegs Ferrothorn and Forretress, and is deceptively strong under the sun. Max HP EVs and Recover make him survive a lot longer, and Max Spe is given to outpace the obvious Shadow Claw coming from Extreme Killer Arcues, who never ever ever invests in full Spe. Ferrothorn (M) @ Leftovers Trait: Iron Barbs EVs: 252 HP / 4 Atk / 252 SDef Careful Nature (+SDef, -SAtk) - Spikes - Power Whip - Leech Seed - Thunder Wave This defensive monster is pretty much a hard counter to Kyogre, Luiga, etc. that used to give me such a hard fucking time when I played with just a pure sun team. However, it takes hits like a champ, and takes a good chunk of HP from Kyogre, and seeing how it only takes around 45% from full power CS Kyogre, can easily cripple the bloated whale with Power Whip to destroy it's effectiveness and regain the HP lost through Leech Seed and Leftovers. Toxic destroys stall-based Pokemon like some Arceus and Lugia, while Thunder Wave cripples speedy threats like Palkia and Mewtwo. It also can be used as sleep fodder if Darkrai is used as a lead against my Groudon. After Ferrothorn is asleep, switch in CS Reshiram and Darkrai can eat shit. Threats: teams that also exploit the Groudon/Kyogre combo really give me hell, and without Taunt Mewtwo, Lugia/Latias really give this team hell, as they can simply recover back entry hazard damage and procede to set up/sweep. THANKS FOR READING :) I really appreciate any help you can give me with this team!
