Hey guys recently I've been watching a lot of yugioh card packs openings and I've gotten this urge to start collecting again. This time around money ain't a problem for me since I'm wildly successful in real life, but I was wondering what packs are the best to buy? I'm also wondering if all packs are full loss or if you can profit from opening yu-gi-oh packs? Just a random question
