You got one of these cards in Japanese TCG booster packs around the time ORAS was released. You would redeem the code on the back in order to participate in a promotion to download legendaries/items/etc. to your game, but I'm only interested in the cards themselves now! (Besides, they've all expired now haha)
These are the last three I'm after!
I'd prefer to buy all of these from one seller, but do comment if you only have one of two of them for sale anyway :) Shipping would be to the UK.
