I'm building a deck and I can't decide whether to go with two types of pokemon or just one. They both have benifits but they also have significant weaknesses.

1 type makes it easy to draw the energy I need. But allows my weakness to be exploited and unless they have a pokemon thats weakness is my type I can't exploit theirs.

2 types makes it hard to balance enough energies and could cause problems when I need say a dark energy but i keep drawing fire.
Though it widens my ability to exploit weaknesses and allows me to switch in and out a defending pokemon with a bench thats a different type to keep extra damage from being dealt.

Any thoughts?

I usually prefer to either keep a half and half deck that can share energies, especially ones that require mostly 'any' energies, or by throwing in a few colorless pokemon cards that need almost no energy. I used to do this with Clefairy, but of course now the general rule is to use only the 'new' pokemon cards so i can't technically do that ; -;

Of course, a fun thing to do is have a few dual type or Delta pokemon, with different weaknesses than the rest of the cards, if you are going for a straight up one type deck. Then again, I haven't really been able to play the tcg in years.... -sigh- more people need to play around here!

Personally, I have a single element deck, but there are a couple of things you could try if you're worried about weaknesses. For one, you could try a deck that is colorless / another element, so that you stick with one energy type but have two elements. Alternatively, you could look for a lot of pokemon that have one element but require energies from another. For example, I think there's a steel magnemite that requires electric energies, or, even better, there's a slowbro that is of water type but is deadly using psychic energy. Using a psychic deck and throwing in that slowbro can help with the energy problem and the weakness problem at the same time.
