Trait: Cursed Body
EVs: 128 Def / 128 SDef / 252 Spd
Timid Nature (+Spd, -Atk)
- Taunt
- Spikes

Taunt, Spikes, and then if at 1 HP use destiny bond to make them switch, Spikes again as they switch out of paranoia, and then Destiny Bond for the kill.

Trait: Prankster
EVs: 252 HP / 44 Def / 212 SDef

Basic Sableye staller, thinking of switching Substitue or WoW for Taunt and Snarl for Knock Off, tell me what you think I should do.

Trait: Cursed Body
EVs: 252 HP / 4 Def / 252 SDef
Calm Nature (+SDef, -Atk)

No surprises here. Once again, WoW vs. Scald, tell me what you think.

Modest Nature (+SAtk, -Atk)

Again, Chandelure sweeper, I just have to watch out for Flash Fire.
Dusknoir (M) @ Leftovers

Trait: Pressure
EVs: 252 HP / 252 Atk / 4 Def
Adamant Nature (+Atk, -SAtk)
- Substitute
- Pain Split
- Focus Punch
- Shadow Punch
This guy has the bulk to take a hit, use Substitute, Pain Split to regain health, and then use the other two moves.
So, any suggestions are appreciated, and I am reluctant to replace, but if you have a really good reason for me to, I will replace.
