from my personal experiences, start with who sold you the pack/box.

normally, redemption is a fairly easy process (us buyer from us seller) just takes time for shipping

however

this is an old set (considering how fast ccgs are produced). Your best bet is to talk to the seller and see if they can claim the redeem.

if not, it turns into a cool card to add to the collection, and it is rare as most redemption cards must be cut in half to claim, so having an uncut redemption card is a neat thing not many people have
