Spdef Excadrill is very anti-meta atm, and this set demonstrates Excadrill's capabilities beyond its pure offensive sets. Dual stab is all Excadrill needs to KO most of what it switches into, including Mega Gardevoir, Mega Diancie, Magnezone, Bulky Rotom-W (watch out for wisp), Clefable, Gengar (for scouting), Latios/Latias, Raikou, non-offensive Zapdos and Specs Sylveon. Toxic allows Excadrill to stop Mega Sableye with help from its ability Mold Breaker ignoring Magic Bounce, and it's also useful for inflicting status on obvious Lando-T switch-ins among other things. Mega Gardevoir and Mega Diancie have difficulty KOing Excadrill with Focus Blast and Earth Power respectively (save for two high rolls from Gardevoir) if you switch in on any of their STAB moves. Without attack investment, Excadrill can still OHKO back and deal serious damage to most of the tier.
Listed as a check because it doesn't like taking Will-O-Wisp, and thus works best with Heal Bell support. Def Clefable has pretty good defensive synergy with this Excadrill set, and since Excadrill is providing spin support you can run something like mono-attacking Unaware CM Clef with Heal Bell.
