Posting first again (maybe it'll pay off this time) with (my personal, not sure about the others') lead Tyrantrum:
Tyrantrum @ Leftovers
Ability: Strong Jaw
EVs: 168 HP / 88 Atk / 252 Spe
Jolly Nature
- Stealth Rock
- Roar / Dragon Tail
- Stone Edge
- Ice Fang
So this Tyrantrum is a lead dedicated to beating Gligar, and for a physical Pokemon it does pretty good! Strong Jaw Ice Fang is a 2HKO on 252/252+ Gligar (it's the minimum attack you can give it), so if a Gligar comes in to Defog/wall it'll be in for a big surprise when you either hit it on the switch and 2HKO, force it out, or hit it while it Defogs and force it out/re-set Stealth Rock. Roar is good for not missing/getting Subs (especially Sub CMers) out of the way while Dragon Tail can get around Taunt, which is pretty big. Stone Edge is good STAB and coverage (it can hit Moltres!).
