Sounds like a fair song of the ghosts of the past.

Yeah. Personally, I don't like Shaymin EX too much. I am sure it is useful but I felt like it encourages a quick metagame as we saw with Seismatoad EX at Regionals. I came into the game right at the tailend/beginning of BW when the game was slowly beginning to speed up.

I don't think any of the future or current decks will want to play Shaymin-EX. I already run a deck that focus on evolution but right now most evolutions seem to be focus as support Pokemon. It would be nice to use Shaymin EX but really it just become a bench sitter and I have plenty of those in my main deck.
