Maybe they should examine why specific cards have fan-made replicas. I've purchased a few of those myself (advertised as custom cards openly) because the cost to buy a real one is absurd: cards that are very old that will not receive reprints probably ever, cards we simply never got outside of Japan at all, cards that feature female trainers because that's an even bigger problem in Japan than here, etc. Throwing a lawsuit in Japan over the ugly gold plated cards everyone should know are fake and are made due to Pokemon's poor pull rates isn't solving anything.
