Here's some sample sets (Taken from a recent rate):
Dialga @ Sitrus Berry /
Lum Berry*
Ability: Telepathy (or Pressure)
Level: 50
EVs: 244 HP / 116 Def / 68 SpA / 76 SpD / 4 Spe
EVs: 252 HP / 60 Def / 116 SpA / 76 SpD / 4 Spe*
Modest Nature
- Dragon Pulse
- Flamethrower / Flash Cannon
- Trick Room
- Protect
*Lum Berry works best with this EV spread
These sets are pretty cool. Moves first though:
Dragon pulse allows you to one-shot a mega salamence with dragon pulse, and it means you don't have to worry about the SpA drop from Draco Meteor whilst under TR conditions.
Flamethrower is the less common coverage move choice on dialga, but it will allow you to get the kill on ferrothorn most of the time, depending on spread choice (2HKO on bulkier variants)
Flash cannon is the more popular coverage move going by usage, and allows you to hit stuff like xerneas which is pretty cool
Trick Room is a fantastic method of speed control for dialga and its team mates, also kinda resonates with the fact that it's a time dragon which i think is awesome
Lum berry is predominantly for smeargle, since you would be losing cresselia, and sitrus berry is for some key benchmarks which i will explain a little later
So the EVs will allow you to do a bunch of things.
The second spread is a little simpler, and will allow you to survive a precipice blades from physical primal groudon whilst simultaneously surviving an earth power from special primal groudon, as well as stuff like draco meteor from mega rayquaza:
- 252+ Atk Primal Groudon Precipice Blades vs. 252 HP / 60 Def Dialga: 174-206 (84 - 99.5%) -- guaranteed 2HKO
- 252+ SpA Primal Groudon Earth Power vs. 252 HP / 76 SpD Dialga: 174-206 (84 - 99.5%) -- guaranteed 2HKO
- 252 SpA Life Orb Mega Rayquaza Draco Meteor vs. 252 HP / 76 SpD Dialga: 172-203 (83 - 98%) -- guaranteed 2HKO
The 244 HP on the second set will reach an even number at level 50, which means that crobat's super fang will activate the sitrus berry, allowing you to survive things that you wouldn't necessarily survive without, such as a precipice blades from physical primal groudon once it has been intimidated etc
What this also entails is that you get to survive 3 precipice blades from intimidated physical primal groudon (i.e an intimidate user would be great on a dialga team, especially with kyogre), which is a surprising benchmark given that dialga is weak to ground type attacks:
- -1 252+ Atk Primal Groudon Precipice Blades vs. 244 HP / 116 Def Dialga: 110-132 (53.3 - 64%) -- 3.5% chance to 2HKO after Sitrus Berry recovery
