It sounds like you collect digital cards like you collect paper cards. Digital cards aren’t collectibles. The mediums are wildly different, both due to the turnaround time on buying and selling and the vendor rake on doing so. If you’re maintaining 1000+ tix of inventory and bemoaning a lack of funds to build decks it’s because you’re treating the system improperly. Just take five minutes to sell what doesn’t go in your current 75 to build your new one.
I’ve seen people tell you this before. I know, I’ve been one of those people. You’re going to be told this every time you whine about card prices.
