Were your trades the starter deck versions or did they come from boosters? Well anyway, you got 4 LV.X for two foreign language ones, plus you got two other playable cards. You won.
If you traded the pack ones, you got a better deal by about 2 Lv.X. 4 would have been enough.
If you traded the deck ones then you really ripped him off. They would only have been worth 2 Lv.Xs.
Ether way, those 2 for 6 Lv.X is a good deal for you.
GREAT DEAL FOR YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Whoever you traded to really got a bad deal! One question though: was the Empoleon Lv.X from the tin or the Booster? Either way,you got the best deal by far!
