>>31094673Decks in the PTCG aren't really built around types. Decks tend to built around a central strategy involving a couple of Pokemon, with the rest of the cards used to facilitate consistent execution of this strategy.
Cards such as Shaymin-EX (draw support) go in almost every deck regardless of the types of the main Pokemon, as typing is not massively important for cards not directly part of the main strategy. As
>>31094262 said, there are cards which work with specific types. However, these tend to be added in depending on what you are already using (as opposed to picking a type to use and then finding Pokemon to fit).
