You seriously Headbutted for this?
Keldeo reminds me of a donkey for some reason.
Bug/Electric is a cool combination, but Bug/Fire is even cooler; one of my old BMGf blogs said that I wanted a Bug/Fire Pokemon. When B/W came, I got my wish, but I was banned so...
As for the Pokemon themselves, I like how Denchura has near-perfect accuracy Thunders with CompoundEyes; it would've been nice if it had more Special Attack.
Ulgamoth is specially oriented, but its pre evolved form Meraruba is physically oriented. You do get a Meraruba egg in B/W, but it's a pain to evolve Meraruba into Ulgamoth because: Meraruba is physically oriented and Ulgamoth is specially oriented. Also, Meraruba evolves at level 59, which adds to the pain. Meraruba loses some of its good Attack upon evolving, but it also gains a lot of Special Attack and learns Butterfly Dance afterward.
