It was probably the worst for me when I was in college. I'd go on Ebay and buy an entire box of cards. There are websites where you can buy individual cards and I'd do that hahaha I played a lot with my friends, both in childhood and in college, but also never played competitively.
40-50 people, that's just crazy. Sounds like a lot of fun though!
Well I look forward to your next game review and will let you know if I get a chance to play any the games that pop up on your feed. Cheers!
