Munkidori (M) @ Black Sludge 
EVs: 4 HP / 252 Def / 4 SpD / 248 Spe  
Bold Nature  
IVs: 0 Atk  
- Trick  
- Protect  
- Psychic Noise  
- Substitute
(Tricking Black Sludge is rude; Using Psychic Noise to inflict toxic is diabolical)

Hoopa-Unbound @ Kee Berry 
EVs: 12 HP / 252 SpD / 244 Spe  
Jolly Nature / Hasty (If running mixed) 
- Wonder Room  
- Hyperspace Fury  
- Zen Headbutt / Psychic  
- Drain Punch
(riffing on the same wonder room hoopa; now mixed.)

Klefki @ Throat Spray  
Ability: Magician
EVs: 252 HP / 4 Def / 252 Spe  
Timid Nature  
IVs: 0 Atk  
- Metal Sound  
- Steel Beam  
- Draining Kiss  
- Thunder Wave
(this was bizzare to use. Magician works after throat spray; steel beam for maximum power; Draining Kiss for item stealing & healing for beam)

Spiritomb @ Choice Band  
Ability: Infiltrator  
Shiny: Yes  
Tera Type: Ghost  
EVs: 248 HP / 252 Def / 8 SpD  
Impish Nature  
- Foul Play  
- Trick  
- Disable  
- Shadow Sneak / Poltergeist / Phantom Force
(Infiltrator + Trick is deadly; Foul Play is the bread and butter here; Disable speeds up games)

Espathra @ Choice Specs  
Ability: Speed Boost  
Tera Type: Psychic  
EVs: 248 HP / 156 SpA / 4 SpD / 100 Spe  
Timid Nature  
IVs: 0 Atk  
- Lumina Crash  
- Foul Play  
- Trick  
- Night Shade
(Speed boost + foul play works pretty well; I have never once used night shade on this set)
