Excadrill

After receiving No Guard from Hawlucha's Entrainment, Fissure and Horn Drill become 100% accurate one-hit KOs against any Ground- and Normal-susceptible Pokémon. No Guard makes what were 30% accuracy moves into unconditional instant eliminations. Mold Breaker ignores opposing abilities for Earthquake. Jolly maxed Attack and Speed creates genuine offensive speed threat. Focus Sash guarantees at least one OHKO attempt even if targeted directly. Earthquake provides spread Ground STAB when OHKO moves aren't needed. The No Guard OHKO combination is game-defining. Any opponent without Ghost typing or immunity faces instant elimination.
