I have been noticing that most of the magazines about CCGs have deck advice
about pokemon, and most of them say you should have more than 22 energy. I
have watched and played tournaments, and the top placers who have
mono-energy decks have less than 23 energy. For instance, I read in Scrye
6.3 about a kid who had a deck called Psychic Infestation, and only had 19
energy. I also have been to tournaments, open trade shows, pokemon specials,
and I have seen players who have pokemon decks that have 22 energy, and that
is dual types. In the end, I am just trying to say that decks don't need so
much energy, and you can fill up those extra spots with whatever you like.

Thank you for your time, and remember, I am just saying this from my own
experience, so don't listen to this if you don't want to.
