Hi everyone, recently, I was testing this funny little guy

with this set:
Diggersby @ Choice Band
Ability: Huge Power
Happiness: 0
EVs: 8 HP / 236 Atk / 12 SpD / 252 Spe
Adamant Nature
- Frustration
- Earthquake
- Foul Play / Fire Punch
- Quick Attack
While I'm aware SM OU is full of breaker that looks way better (Kartana, Tapu Lele, ...), I still believe a lot in Diggersby. One of its biggest appeal is Frustration. This move is extremely free to spam and, on practice, a lot of balance struggle to switch on Frustration + Earthquake (especially with recent trends using core such as Cresselia + Toxapex). Moreover, even if you fail to predict, the damage output of Diggersby is nuts and it will deal a ton of damage on most normal-resist:
-

: 236+ Atk Choice Band Huge Power Diggersby Frustration vs. 252 HP / 24 Def Ferrothorn: 123-144
(34.9 - 40.9%)
-

: 236+ Atk Choice Band Huge Power Diggersby Frustration vs. 252 HP / 252+ Def Skarmory: 90-106
(26.9 - 31.7%)
-

: 236+ Atk Choice Band Huge Power Diggersby Frustration vs. 132 HP / 0 Def Tyranitar-Mega: 111-131
(29.6 - 35%)
Diggersby can also run a lot of different options such as Spikes, U-turn and Knock Off. Imo, Quick Attack is really useful to deal with the likes of Volcarona and Mega Swampert while giving a potential winco. Foul Play is also neat to offer a nice midground into Landorus-T + Heatran core while having a neutral move to hit the likes of Celesteela and Kartana:
-

: 0 Atk Choice Band Huge Power Diggersby Foul Play vs. 252 HP / 24 Def Celesteela: 196-231
(49.2 - 58%)
-

: 128 Atk Choice Band Huge Power Diggersby Foul Play vs. 128 HP / 0 Def Kartana: 294-347
(101 - 119.2%)
Finally, Diggersby provide an essential immunity to Electric-type and, even with the Adamant nature, is fast enough to outspeed Modest Heatran.
In term of structure, I didn't try any kind of Diggersby + Magnezone core since I dislike Magnezone on anything not named Balance. After some tests, my conclusion was that the optimal playstyles with Diggersby is somewhere between BO and Balance. I will show two teams I liked with Diggersby then explain some cores that seems ideal if you wish to use the funny bunny:
-Diggersby + Mega Latios BO:

Very straight-forward team. Diggersby + Spikes Ferrothorn pressure a lot Mega Latios's checks. Fast Zapdos offer much more flexibility into Mega Scizor and pretty much anything. Overally, cool team but feels like it can be improved somehow.
-Diggersby + Mega Charizard Y Offense:

It's basically ABR sun offense but with Diggersby over Weavile. The idea here is that Fire Punch under sun melt Skarmory for free meaning Diggersby + Kartana will cover most Balance MU while Mega Charizard Y will carry Offensive MU. Not a great team but still alright.
Like I said, I will put some words about the cores I think are ideal if you want to build with Diggersby:
-

+

: I think those two are pretty solid since Tapu Fini likes the Ground-type provided by Diggersby while Tapu Fini cover the Water and Fight weakness of Diggersby's Normal- and Ground-type. Finally, misty terrain is really useful to helps Diggersby to switch more easily on the field.
-

+

: Spikes support is crazy to completly fuck up any slow builds. Moreover, Ferrothorn cover the Grass and Water weakness of Diggersby.

: Having a fast mega to force reactions from the opponent and use them to give opening to Diggersby is the best way to use it imo. Mega Diancie offer more momentum with Magic Bounce and Mega Latios provides more defensive value (which cover nicely Diggersby's weakness).
That's all for today. How you enjoyed the post and S/O
