I'm afraid that we are unable to transfer a TCG item to a different character once it has been claimed and bound, Hawkn. My apologies.
If you'd like to see these items be transferable to other characters on your account I encourage you to make a post on the Suggestions Forum.
If you're finding yourself unable to redeem unused codes, please disable your addons and try once more.
