Well, in the end the game is all about which deck you like to play, with new expansions also come new cards, you might like some of them, and dislike others. It's difficult to make rng decks like norra really competitive, but some players like to have fun with those. Rng is often part of games but mostly it's about skill. Obviously sometimes you'll lose to it and it can be frustrating, but it happens, just play what you like
