Why would you tell your opponent what type of deck you play with?
Anywho...
My box finally arrived, and like the Legend Maker box I purchased, I really got more than my money's worth on it. I was kinda shocked - perhaps Nintendo is being generous?
Nothing in the set, at least in what I received, would make a killer deck combo. Golduck has possibilities, and Mew EX could be somewhat useful if you had a way to get energy back into your deck from your discard pile. The fact that there aren't really 2-3 really good deck cards in this set might explain why the box prices average around $60-$65 now. Some sets, like Unseen Forces, really skyrocketed in price once people saw all the EXs that were availble in the set.
One thing I have noticed is that the "reverse holo" style format is not very popular with collectors. Normally, holos can go for $4-$10 depending on character and attacks. But the Delta Species types generally go for much less.
