Now I love this game. I grew up with Yugioh and this is arguably the most polished virtual version of it. But, it's extremely grindy. It takes hours to earn the gems required to buy more card packs. On the one hand it's nice to have something to strive for, on the other it's painfully annoying if you're trying for certain cards (which many decks now have a few key cards that make the deck). Plus major connectivity issues that people have complained about for a while but it hasn't been fixed
