Lucario @ Life Orb Justified Adamant (+Atk, -SpA) 252 Atk/252 Speed/4 HP -Swords Dance -Close Combat -Bullet Punch -Extremespeed Mamoswine @ Life Orb Thick Fat Adamant (+Atk, -SpA) 252 Atk/252 Speed/4 HP -Ice Shard -Earthquake -Superpower -Icicle Crash Tentacruel @ Black Sludge Rain Dish Timid (+Spe, -Atk) 252 HP/240 Def/16 Spe -Substitute -Toxic -Rapid Spin -Scald The idea of this core is to set up the Lucario sweep. Mamoswine takes out Landorus, Gliscor, Dragons, Breloom, Virizion, Torandus, Thundurus-T, Venasaur, and anything else weak to ice shard. Tentacruel counters all the scary fighting and fire types throwing attacks at Mamo and Lucario, and can sub up and spread toxic/burn at anything else. It also can poison Volcarona and wear it down with scald. The only pokemon not easily countered by this core that I can think of off the top of my head are Jellicent, Celebi, Conkeldurr, Genesect, Reuniclus, Scarf-Jirachi, Keldeo, and Vaporeon. Not bad for just 3 pokemon if I do say so myself! This core is versatile enough to be very successful in rain and hail (I've used it in both to good extent) or just weatherless. Thundurus-T is a great addition to this core for its ability to OHKO most of the pokemon on that short list of threats. Stealth Rock support is also helpful for Lucario to sweep more effectively. Anyways, that's my core! I like it because it's not too standard or common but it still wreaks havoc on most of the metagame.
