Well Konami which is the people that made the game had him sign some cards. In every pack there was a chance to get a signed card!!! and so there are some signed cards out there!!
Hi I was wondering if anyone would be interested in a card signed by Kentaro Miura? It’s a Berserk tcg card and I will post a picture of it here. If anyone would like to contact me about price just shoot me a message on here!
