Escavalier
Typing: Bug / Steel
Base Stats: 70 HP / 135 Atk / 105 Def / 60 SpA / 105 SpD / 20 Spe
Abilities: Swarm / Shell Armor / Overcoat
Escavalier is a force to be reckoned with, as its base 135 Attack will easily pierce any defense especially when boosted by a Choice Band. Escavalier is commonly seen utilizing a Choice Band set because of the sheer power it brings to the table. A Choice Band-boosted Megahorn will punch a hole in any Pokemon, even some that resist it! For coverage, Iron Head takes advantage of Escavalier's secondary STAB. Pursuit is an awesome way to trap fleeing Ghost- and Psychic-types, especially because Escavalier's typing allows it to switch in easily on their STAB moves. The last slot typically seen is either Return or Sleep Talk. Return just hits neutrally on anything that might resist Escavalier's dual STABs. On the other hand, Sleep Talk allows Escavalier to take a Spore or Sleep Powder and not be dead weight. To make matters better, as Escavalier gets worn down, Swarm can activate to power up Megahorn even more!
Defensive
Typing: Bug / Steel
Base Stats: 70 HP / 135 Atk / 105 Def / 60 SpA / 105 SpD / 20 Spe
Abilities: Swarm / Shell Armor / Overcoat
Escavalier's excellent typing allows it to successfully combat special attackers. Its typing allows it to successfully counter Lilligant, Slowking, Tangrowth, and Jynx, if they lack a Fire-type attack. The standard defensive moveset would have Megahorn, Iron Head, and Toxic. The dual STAB attacks allow Escavalier to hit decently hard thanks to its base 135 Attack, and Toxic fulfills the purpose of slowly wearing down opposing Pokemon. Escavalier can be even more dangerous depending on its last attack. Rest + Chesto Berry ensures that Escavalier will be around for a long time, and it can also utilize Rest and Sleep Talk.
