nature : Naughty
evs : 204 Atk / 156 SpA / 148 Spe
Why this set deserves to be on site:
- Best mixed sweeper in Ubers with zero counters at +2/+2.
- Resists common priority attacks,namely Extremspeed,Shadow Sneak and Bullet Punch,which is vital for a sweeper
- Has great resistances and physical bulk which enable him to take a hit if needed when baton passing the boosts to him
- Does not care about T-Spikes which is great for a baton pass receiver
Additional comments:
- Life Orb is vital to this set as it enables a lot of kos and is the only possible item.
- This set is obviously designed to sweep with +2 boosts in attack,s.attack and speed.The easiest way to achieve this is from a shell smash passer,and the hardest way is from an entire batton pass chain.
- The attack evs are enough to ohko ubers Bold Chansey after SR at +2 with Brick Break,while the speed evs allow Dialga to outspeed everything up to ScarfChomp at +2.Rest are dumped to SpA but they are also vital 'cause they achieve many ohkoes.
- Entry hazard support is vital to this set success,as with 1 layer of Spikes and SR absolutely nothing can survive its attacks!
- An alternative spread of 96 Atk / 236 SpA / 176 Spe,with a Rash nature,can be used with a moveset of Outrage,Dragon Pulse,Aura Shere and Thunder/Thunderbolt.The attack evs are to ohko standart ubers Bold Chansey after SR at +2 and the speed evs are just enough to outspeed scarf Terakion at +2.

Teammates & Counters:
- Shell Smash Smeargle is the best teammate for Dialga and is absolutely necessary in order for Dialga to function properly,except if you want to build a dedicated baton pass team.
- Other Shell Smash passers like Gorebyss and Huntail are also good partners but they lack the invaluable Spore,so Dialga will have to watch out as he receives the boosts.
- If you are running the second spread with Thunder,Kyogre is a very good partner to esnure that it will hit,so that opposing Lugia cannot screw you.Kyogre can also deal destroy the only poke that can take a hit from this Dialga which is S.Defensive Jirachi in rain.
- Deoxys-S is also a perfect partner to this Dialga as it needs SR and 1 layer of Spikes to secure some ohkos.
- As mentioned before the only poke capable of taking one hit from this Dialga is S.Defensive Jirachi.
- Scarf Darkrai,Scarf Mewtwo and Scarf Shaymin-S can all outspeed Dialga and ohko him at -1,but fortunately they are rare!
- If sand is up Excadrill outspeeds you and ohkoes with EQ.
- Finally you should always be careful of phazers when trying to pass to Dialga.Restalkers that can phaze,Giratina and Dialga in particular,can be problematic since they can phaze you even if you put them to sleep with Spore so you should watch out.
