Got this after getting back into the old school tcg, safe to say I'm happy. Deck building is simple, visuals are slick, it just feels like yugioh. People who haven't played yugioh before and don't have a basic understanding of the game and its principles could have trouble starting off, but it doesn't take long to get the hang of things. Plus, it's all completely free! (Except the optional in app purchases, which are all for things you can buy with in-game currency, which can take time to earn).
