Various questions:

Can Pikachu ever be bred to be competitive?
If not, can Jolteon work, or should I just give my Gardevoir Thunderbolt and call it a day?

Is there a way to teach Arcanine Flare Blitz? I stoned mine soon as I learned Crunch and kinda regret not waiting for it now.

Is there a "good" normal type pokemon to use? I want it to be a HM whore but at the same time be fun to use. I noticed my Adamant/Proud of its Power Pidgeot was doing tremendous amounts of damage with Return and maxed happiness
