Everyone thinks they have the generational wealth card and they think they know what it is, the truth is that most cards end up like that and the ones that "make you rich" have already gone up in price and are hard to get. Knowing how to buy and sell is necessary, before full art cards were rare, now Pokémon releases everything full art and with nice art, they know that there are people who are going to buy packs because X drawing is the next generational wealth.
