this dosent seem to be an ICO or altcoin, i think you should post this in the marketplace and specifically the collectibles section (
https://bitcointalk.org/index.php?board=217.0)
it wont get much attention on this board, just bounty hunters :/
I am very interested, but the lack of apparent OTHERS interest for this awesome collection is worrying, will you consider a forum escrow till physical delivery of cards?
Good Luck on the sales, if ETH wasent a headache to use for payments with the gas thing i would buy like 5 of these, consider accepting BTC as well maybe!
