Revamped multiple weather uber team
This is just my revamped multiple weather uber team because i think my old multiple weather team has been dead. I never used or tested this uber team but i think this team may work decently if Arceus isn't allowed (Arceus usally not allowed anyway) If Arceus is allowed, my team will 6-0ed by them seriously. My team's sweeping is started from Mixed Dialga ,who is big 5 on current uber metagame, (I read train man's analysis of uber metagame and Jibaku and Great Sage's guide to ubers) he break or loosen enemy wall to make my other teammates sweep much easier. Just difference between normal Mixed Dialga is EV and Nature, which i taken from KinglerDude's Uber RMT (Sorry) Darkrai make Groudon (Maybe Rayquaza since i am stucked between choosing Rayquaza or Metagross) sweep much better and cripples Lugia and Giratina. Kyogre is Boosting RestTalking Tank who assist my team countering SD Groudon since my team don't have Lugia to counter Groudon anway. Latias is Healer, Special Sweeper, Special Wall, and non-choice Palkia counter. My team's groudon is taken from Ike and Tina and Train Man's uber thread (Sorry also) I think Metagross would be preffered choice since it counter Lati Twin and Deoxys-A nicely but with Darkrai support using Rayquaza wouldn't be bad idea. I think my team's problem would be Deoxys-A, Palkia, any Dialga except BU version, Weavile (Which is very unpopular), Spike/ toxic spike/ stealth rock, and most notably CM Kyogre. KinglerDude's thread really helps me building this team since i got his Mixed Dialga's EV and idea of using SD Lugia.
Groudon @Leftover
Ability: Drought
Nature: Adamant
EV's: 252 HP / 156 Atk / 32 Def / 60 SpD / 8 Spe
-Toxic
-Stealth Rock
-Earthquake
-Dragon Claw
Role:
Sort of Physical Wall and supporter. Supporting Groudon is phenomenal and i think best set of Groudon. Toxic cripples supposed to be counter like Lugia and Cressleia by poisoning them and make them pretty useless. Stealth Rock helps to fight against Rayquaza, Lugia. STAB Earthquake still does good amount of damage to anyting that aren't immune to or resistant to thanks to his high attack and dent Dialga, Metagross who are immune to Toxic. Dragon Claw dent foolhardy Rayquaza, Lati Twin switch-in. He also brought reasonable counter to DD Jolly Rayquaza, Metagross, BU Dialga, and Tyranitar. DD Adamant DD Rayquaza might be threatening but my Choice Scarf Palkia can revenge kill them. This EV ensure that Lugia's Ice Beam is a mere 4HKO giving you ample time to set up Stealth Rock and Toxic. Groudon is also, only dealt a 3HKO by Latias' Dragon Pulse after factoring Soul Dew and Leftovers and Groudon cripples their durability with Toxic.
Dialga @Expert Belt
Ability: Pressure
Nature: Mild
EV's: 136 Atk/252 SAtk/120 Spe
-Draco Meteor
-Brick Break
-Thunder
-Fire Blast/ Earth Power
Role:
This is exact carbon copy of KinglerDude's Mixed Dialga. This Speed EV ensure most Mixed Dialga found in uber metagame. Setting Up stealth rock if Kyogre are likely switch out. Dragon+FIghting+Electric already have good coverage so using Stealth rock is not oxymoron idea.
Rayquaza @Life Orb
Ability: Air Lock
Nature: Adamant
EV's: 32 HP/ 252 Atk/ 8 SpD/ 216 Spe
-Dragon Dance
-Outrage
-Earthquake
-Extremespeed
Role:
Late Game Sweeper. If he has stealth rock from my Groudon, Lugia is pretty locked since he is OHKOed by STAB Outrage. Earthquake is for taking down Metagross and Dialga. Extremespeed is for taking down Deoxys-A or random Ninjask. Overheat to taking down all steel type poke. Maybe he will give my team extra Dragon Problem but his sweeping with Stealth Rock is very tempting and he will be fine if Groudon and Kyogre counter Metagross or other steel who are resistance to Rayquaza's STAB Outrage.
Kyogre @Leftover
ABility: Drizzle
Nature: Bold
EV's: 240 HP / 244 Def / 24 Spe
-Calm Mind
-Surf
-Rest
-Sleep Talk
Role:
Groudon counter, special sweeper, and special sweeper. Even Blissey can't ensure defeating this big, big whale since she have 50/50 chance of winning this with help of Psych Up. However, weak to Rayquaza, Latias, Dialga.
Palkia @Choice Scarf
Ability: Pressure
Nature: Hasty
EV's: 6 Atk / 252 SpA / 252 Spe
-Aqua Tail
-Surf
-Thunder
-Spacial Rend
Role:
Mixed Sweeper and revenge killer. In rainy situation Aqua Tail 2HKO Blissey and make her useless to absoring special attack from this guy. Surf is very painful under rain. Not even Kyogre is a safe switch in to that, as it may 3HKO. Surf also puts a gigantic dent in Dialga and non Water, Grass or Dragon Arceus, 2HKOing both of them easily with Choice Specs. Thunder puts a big dent in Kyogre and still 2HKOs it even if Kyogre Calm Minds. Spacial Rend 2HKO Latias while outspeed them. Also, this thing helps fighting against Deoxys-A because he will tie or sometimes outspeed them and kill them while he doesn't kill by it unless it use Psycho Boost.
Blissey @Leftover
Ability: Natural Cure
Nature: Bold
EV's: 4 HP/ 252 Def/ 252 SDef
-Icy Wind
-Toxic
-Counter/ Wish
-Recover
Role:
Special Wall and Kyogre counter.
