So here's the thing.
I'm playing through X and Y. and I need my last pokemon slot filled. Here's the current mons

Relicanth (Water/Rock)
Froslass (Ice/Ghost)
Cacturne (Grass/Dark)
Baltoy (Ground/Psychic)
Skarmory (Steel/Flying)

so that leaves me with 8 other typings.
I want to cover as much as possible.

I don't know what to get, i'm torn between a Dragalge, Dedennde. Or some other pokemon with a typing I don't have.

and why the fuck isn't there a fire/electric pokemon
