I would just like to offer an aside and say that Subtect Gliscor is the greatest staller ever invented.
Gliscor @ Toxic Orb
Poison Heal
Impish
252 Hp/ 176 Def/ 80 Spe
Substitute
Protect
Toxic
Earthquake
Toxic the opponent and the alternate between Substitute and Protect. During these 2 turns, Poison Heal will completely heal off the damage Substitute causes, while the opponent is slowly worn down by Toxic. The only way an opponent can bypass this strategy is to Taunt/ phaze, and even then, they're still taking damage from poison. It also just so happens that the only pokemon immune to poison are steel types, poison types, and poison healers. Earthquake conveniently hits the first two for SE STAB damage. Meaning the only pokemon Gliscor can't touch are Breloom and Gliscor between EQ and Toxic.
This set needs to be used more. That SD Gliscor isn't getting any sweeps, like, ever. Its also not exactly the most reliable way of checking Conkeldurr since it could just Bulk Up as you Protect.
