I'm working on something that I should be able to post sometime within the next couple of days. Hopefully you guys will like it.
So, something fun that I've been using is this core:
Shuckle @ Banettite
Ability: Sturdy
EVs: 248 HP / 8 Def / 252 SpD
Calm Nature
- Sticky Web
- Stealth Rock
- Encore
- Protect
Sets up prankster webs, can encore set up sweepers, and is really annoying
Thundurus (M) @ Pinsirite
Ability: Defiant
EVs: 252 Atk / 4 SpA / 252 Spe
Hasty Nature
- Return
- Wild Charge
- Volt Switch
- Superpower
Discourages Defogging with defiant, turning into an EXTREMELY deadly sweeper with a single boost.
Or you can use bisharp, but that's less threatening.
Diggersby @ Medichamite
Ability: Huge Power
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Earthquake
- Quick Attack
- Return/Wild charge
- Swords Dance
The main sweeper the webs are for, if diggersby gets the chance to set up an SD, or even freely mega evolve, it becomes a major threat.
Good partners for the core:
A T-Wave user is appreciated, to slow any levitators/fliers, as well as for the chance that webs get removed.
An -atespeeder is quite useful here to pick off any faster threats, and take care of other -atespeeders like dragonite.
A cleric is always helpful to pass wishes, heal status, etc. I would recommend Aggronite togekiss for this one, as it can do all of these, and provide defog support if necessary.
Any mid-speed sweeper really loves sticky web,so fitting in one of those can help as a backup sweeper.
