I'm making a deck with 2 types. So that advice isn't going to help me out.Those are two completely different decks though. If you wanted to, you could play your traditional Fairies deck with Xerneas, Aromatisse, and Rainbow Energy with the idea being to just move the Energy onto Groudon whenever you get enough Rainbows in play, but Faries without Groudon is a deck and then Groudon is another deck. If you try to combine them together, the deck isn't going to have focus.
