What is up everyone, hope you like the original title of this thread. Diancie+fire-mon-with-quad-rox-weakness is a cool concept that I tried to make work with volcarona in OU, but I didn't have much success, so I moved to ubers where rainbow bird is a top threat and not a "go big or go home" kind of pokemon like volcarona. The teambulding was not straightforward indeed I kept shuffling around the last two teamslots and some sets until I was confortable with the team.
Diancie @ Diancite
Ability: Clear Body
EVs: 76 Atk / 252 SpA / 180 Spe
Timid Nature
- Moonblast
- Diamond Storm
- Earth Power
- Protect
Diancie is the first mon added to the team and so far it has pulled its weight in every match. It sports really good coverage in the form of diamond storm, moonblast and earth power, which is useful to deal some serious damage to primal groudon and klefki.
Evs are standard and quoting the smogondex "176 Speed EVs with a Timid nature allow Mega Diancie to outspeed base 100 Speed Pokemon. A Timid nature is used because the Attack drop does not significantly impact any targets of Diamond Storm [...]. Significant Special Attack investment keeps this set offensive and allows it to OHKO threats such as Rayquaza and Mega Salamence. The remaining EVs go into Attack to make Diamond Storm hit slightly harder."
Ho-Oh @ Choice Band
Ability: Regenerator
EVs: 248 HP / 188 Atk / 52 SpD / 20 Spe
Adamant Nature
- Brave Bird
- Sacred Fire
- Earthquake
- Sleep Talk
Ho-oh is the special tank of the team. Dual STABs are mandatory for every set as brave bird has good coverage in the tier and the secondary effect of sacred fire is really good. The last two moveslots depend on the set you want to run and can be either recover+twave or eq+sleep talk. I can't really decide which set I should run. Twave is useful to cripple salamence on the switchin, while thanks to sleep talk I have sleep fodder for darkrai (I can't really bank on diancie to check it for the whole match).
EVs are just enough to survive thunder from a boosted geoxern, 20 speed EVs for speed creeping standard Ho-oh (winnig a potential mirror 1v1 could help a lot considering that I don't have good switchins), the rest goes into attack.
Groudon @ Red Orb
Ability: Drought
EVs: 252 HP / 56 Def / 200 SpD
Relaxed Nature
- Stealth Rock
- Earthquake
- Lava Plume
- Thunder Wave
Groudon is the team supporter that checks a lot of stuff. Earthquake is chosen because I prefer accuracy over power. Lava plume is another good STAB with a nice secondary effect. Sometimes I wish I had stone edge for opposing ho-oh and salamence but lava plume has its merits. Thunder wave is what I'm running for neutralizing mega mence on the switchin.
The EVs are standard for a defensive set, but I suppose that a sassy nature might be viable to take better ice beam from kyogre and some hits from geoxern.
Latias @ Soul Dew
Ability: Levitate
EVs: 212 HP / 120 SpA / 176 Spe
Timid Nature
- Defog
- Roost
- Draco Meteor
- Grass Knot
Latias is yet another team supporter and it's really good at switching in on the primals and arceus ground and consistently getting a defog off. The only issue I have with latias is it is usually setup bait for E-killer after the SpA drop from draco meteor (which you are going to use quite often given that is the only powerful STAB on her set).
EVs are straght from the latias analysis and allow her to outspeed base 100s. 120 SpAtk were used to 2HKO kyogre with psyshock and the rest went into bulk. Even if I don't carry psyshock I didn't know which benchmarks I should have used for this set so I left everything as it was.
Mewtwo @ Life Orb
Ability: Pressure
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Psystrike
- Focus Blast
- Ice Beam
- Taunt
Mewtwo is the new entry and let me say just one thing about it: it is so good. Psyshock deals heavy damage to pretty much everything in the tier. Focus blast is chosen for coverage against steel types and dark types, ice beam smacks the dragon types in the tier and yveltal, taunt is crucial for preventing rocks. Of course dropping fire blast sucks for stuff like klefki, scizor and aegislash, but I feel safe with two fire types on my team.
EVs maximise offensive potential.
Arceus @ Life Orb
Ability: Multitype
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Swords Dance
- Extreme Speed
- Shadow Claw
- Earthquake
E-killer is yet another broken pokemon that mauls stuff yada yada you know how it works. Extreme speed is very useful for revenge killing stuff and shadow claw hit hard the ghosts that threaten latias and mewtwo. Earthquake is standard coverage for groudon, dialga and diancie. SD and life orb allow arceus to wallbreak effectively.
EVs maximise damage output.
latios: I don't have a good switchin. It's usually a guessing game between psyshock and draco meteor and I have to think twice before sending out either diancie or mewtwo.
salamence: without a twave on either Ho-oh or groudon earthquake sets literally 6-0 this team.
E-killer: not much to say it has some setup opportunities and it's just really difficult to stop once it gets going.
giratina: not a threat by itself, it needs some team support, but a well played giratina can screw up latias, groudon, mewtwo and arceus, especially if it's a hex set.
gengar: really annoying, It's really scary if it carries protect to mega evolve safely.
groudon: dual dance variants are the evil.
To my offensive core I added groudon, which checks kyogre and provides rocks support; next teamslot was a toss-up between the lati twins, I eventually opted for latias for her better bulk, which allows her to check some threats more reliably than latios, but sometimes I miss the power. I asked in the ubers chatroom what I should have put in the last teamslot and someone suggested to put defensive yveltal and arceus-water, so I did. The team performed well but sometimes it felt really passive. Then I used klefki+E-killer; the only issue I was facing is that opposing groudons were consistenly getting rocks up, so I searched for a mon with taunt in the uber tier and mewtwo seemed a good fit, revenge killing some threats that klefki used to check, like mence, latis and darkrai.
