Here's an interesting core I've been experimenting with.
Nidoking (Gengar) @ Life Orb
Ability: Sheer Force
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Shadow Ball
- Sludge Wave
- Focus Blast
- Taunt
This set looks simple enough to use. Taunt allows you to beat the blobs, unless they're Sableye clones... which are trapped and killed by this:
Gothbuffet (Wobbuffet) @ Choice Scarf
Ability: Shadow Tag
EVs: 252 Def / 252 SpA / 4 Spe
Modest Nature
- Trick
- Rest
- Calm Mind
- Psyshock
The EVs maximize overall bulk after you've set up to +6 and killed the blob that you had trapped.
Here's the core in action.

How does that Wobb beat Sableye Chansey? It just gets taunted, and its Psyshock is too weak to do anything of note.
