Flygon ex df $20 max
Mew star $25
Empoleon Lv X $8 (This card has zero demand, the tin cost $14 and the art is better)
Total: $52
Darkrai Lv X JPN is going on ebay around $70-80
Thats a price scale but on play ability scale, the I gave are almost useless:
Flygon ex df - The only deck this works in is Electragon, only 1 is played and this cards is easy to get.
Mew star, ad a deck card, theirs no decks for it, it was ok in infercatty as a mirror tech, but that deck alredy went from the best to the worse, well not the worse but bad, mostly cause of Empoleon and Hurricane, this card is still nice to have.
Empoleon Lv. X - No matter how good this card, even if it is the NUMBER ONE, it will never be more than $14, never unless the tins have no stock left or something like that, but this card is not that good.
So I think it was a nice trade, but everybody has their point of view.
