Im really not promoting nothing, read my previous comment whole, I was talking about that with paying sub for WoW to Blizzard some nowadays people seems to think they should have with it automatically access to unique/unobtainable stuff from the past aswell, which is just ridiculous.
Yes, some one of them are expensive (if we can talk about Spectral Tiger or other TCG stuff) but prices for it are determined by people itself, because there is limited amount of them and people just naturally put value in it, it is a very common thing no matter much now if the thing itself is physical or digital - but anyway many players got most of the TCG stuff by common way from buying TCG cards back then when they were actual, many of them didnt buy it for real cash for high prices like we can see nowadays, thats rather more of an exception if someone really buy it for thousands of dollars, but as I said its because there are just few of them left nowadays. I personally wouldnt really buy it for such high price, but thats everyones business
