maybe 5 each still but all foil? (daring to dream)
maybe the second set of 5 energy per type could be foil.
The problem now is the playmat. They would have to redesign the box to fit the playmat, and I don't know how that is going to work. It would mean the players guide, which I like the size and shape of, would have to change, and become smaller, like the size of the players guide for the World of Warcraft Trading Card Game Epic Collection, and that is the size of a pocket book.
I voted for to keep it the way it is with 2 releases per year, but seeing how MTG always releases fat packs every set, and there is a Primal Origins Deluxe Edition, I feel like I want an Elite Trainer Box every set because it follow suit of those two. Heck, throw in a 9th booster pack as well. Oh, don't forget the rulebook, you know, the thing we used to get with theme decks before Black and White came along?
For now, how about releasing an Elite Trainer Box for Flashfire, and then the set after that, to see what people say about it? If they had to release two per year, I'd rather have them release it in February and August, so release the Elite Trainer Boxes in February and August sets as it always has been, and just release another one in the May set, just to see the public reaction. If they hate it, then don't release them November 2014 and May 2015 and any following May and November, but if they love it, then release one in November 2014, after the one in August 2014, and continue to release one every set.
Also for starters, before doing anything too big, just include the theme deck playmat/rules sheet in it. After that, they can figure out how to do the cloth playmat for one of 4 Elite Trainer Boxes per year, and switch to the actual rulebook.
Again, this is the most important piece. An all holo preconstructed deck, containing pokemon from multiple sets, released in June, and a VS deck featuring EX cards as cover cards, with pokemon from multiple sets, tied with the movie, released in December, or whenever the movie was supposed to come out.
