Ok, you need a grass Pokemon. A grass Pokemon would destroy that Sesmitoad. I'd suggest catching the Virizion which would destroy Sesmitoad, while beating up his biggest threat, Hydreigon, if you beartic dies. Ferrothorn would be a fine second but you HAVE to go first. IF Sesmitoad uses earthquake on you're ferrothorn. Other grass types are Leafeon, Roserade, Tangrowth, Carnivine and Tropius. Will add as I go. As a bonus, I'll help you defeat the rest of the team. I'd take out Fracture, as it isn't that useful. I'd switch it for a psychic to take out that Toxicroak, which can be devastating to your Absol. Well, you've covered most, and BTW, I'd take out Ampharos for the Virizion. This would also cover Hydreigon AND Drapion. So that leaves unharmed Electross. But i'm not going to take another Pokemon out so you can attack Electross better. I'd suggest giving Absol dig, or any Pokemon dig or Earthquake.
