Darmanitan, his monster attack stat coupled with pretty good speed and Flare Blitz make an unstoppable rape train
>Water
Jellicent, he has great defensive stats, abilities and movepool, as well as a pretty good offensive side
>Grass
Whimsicott or Lilligant, Whimsicott is the best annoyer in Gen V and with the right setup can easily take down 1-2 Pokemon depending on how your opponent moves, while Lilligant has a very special niche in Quiver Dance + Petal Dance + the inability to be confused
>Fighting
Every Fighting type is good OP. You can choose any and you won't be let down.
>Dark
Same thing. Depends on what you want specifically, Liepard is an annoyer, Scrafty is a fast and good hitter, Bisharp has a bad weakness in Fighting but everything else is fucking great, and Krookodile is all around pretty good
>Steel
Same thing as Dark and Steel, though I've never used Klingklang
>Psychic
Reuniclus is amazing if you can work around its 30 speed
>Ground
Golurk and Krookodile are very good offensive Pokemon, Golurk hitting especially hard
>Electric
Emolga is annoyer, Galvantula is mixed attacker
