I went on Amazon and ordered a business card [display holder](https://www.amazon.com/Business-Acrylic-Desktop-Holders-Exhibition/dp/B093BTZ68C/ref=sr_1_4_sspa?keywords=business%2Bcard%2Bdisplay&qid=1652704152&sr=8-4-spons&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExOFI4REg5T0E2MTFIJmVuY3J5cHRlZElkPUEwNDExNT... for something like$10. I put each of the region decks on one side and the gates, expedition and destruction decks on the other side. I set the whole thing next to the board and it takes up little room. For discarding I just put the cards behind the deck facing the opposite direction.
I've found that with a little innovation and imagination you can save a ton of money on storage options. And with some creativity you can even keep the thematic feel going on. Like my card holder is black and y wife painted some thematic images on the sides. And I story my game in a wooden crate I found at a thrift store. I bought a couple of trading card boxes to story the cards in and some cheap Plano boxes for tokens.
Sure, link to first one I found on Amazon is here. So instead of having 6-8 decks of cards spread across a table you can have them all organized in a small foot-print.
I bought this game used and it came with the chit containers. But the card stand is wonderful, it’s a business card holder I’ve repurposed. Gowall Business Card Holder, 8... https://www.amazon.com/dp/B093BTZ68C?ref=ppx_pop_mob_ap_share
