So this is mono-poison + Politoed. A fair team considering what all you can do with that.

A slightly different approach to my usual Politoed. It's really based on " Please... get the burn.... ". Along with some nice " screw you dragons " and other random utilities.

Toxic Spikes can support my future Venoshock abuser(s), while also giving me some hazards on my side. What's a mono-poison team without tons of annoying poison crap to get through, right? Hydro Pump gets dat STAB, dat rain boost, and dat nice power. The accuracy really doesn't bother him too much. Giga Drain is really used for the recovery on opposing water types I can't really hit well with hydro pump. Rapid Spin removes hazards to help the rest of my team!
Ability: Dry Skin
EVs: 252 HP / 252 Special Defense / 4 Attack
Dry Skin gets a lot of nice rain support here. Bulk Up + full special bulk invest = bulky frog thing. Drain Punch also makes this combo amazing. Ice Punch takes dragons out of the picture, and sucker punch punishes psychics while giving me priority.

HP Rock ( 60 base so Technician will make it 90 base )

Acrobatics is amazing STAB, especially when paired with Flying Gem. U-turn allows me to scout around a bit. Roost allows healing, and you can actually make decent use of it with Crobat's typing. Super Fang is for wall breaking.

He's a great sweeper. Shadow Ball will be reliable STAB instead of Hex which is really only good when my opponent has a status condition. Venoshock is solid and amazing when my toxic spikes has gotten to opponents. Thunder + HP Ice is basically bolt beam. Only it's like a took some power from Ice Beam and gave it to Thunderbolt :3
