Export of cards owned

If deck building is to be something that everyone can truly capitalize on and build a deck best for them, they need to know what they own. Unlike MTG Arena, you can truly export everything you own into an Excel sheet and utilize it, or export it in a way that allows you to know what cards you own versus don't. If we are going to be so restrictive and not allow players to realiztically know what cards they do or don't own, even if it is foiled/rare/etc you are not going to succeed, and players will revert to other TCG games online. I'm sorry, the Pokemon community, regarding multiplayer games, has become a bureaucratic onslaught of those who "can" versus those who "cannot."
