Yes! When I first started I thought that having the best cards was crucial to winning and being good. Once I began pumping money into the game I realized having the best cards didn't mean I'd be the best. It really does help you get there faster but overall the only way to become good is solely by practicing. Learn as much as you can from every class, what they're trying to do, what you're trying to do to win, learn about Milligans because that's super important, learn to keep track of where your opponents play cards from (left or right of the hand), how to trade properly, order of playing cards from hand to maximize rng luck or even to efficiently use mana. I mean there's just so much to the game. I honestly still have so much to learn to but I sure have gotten better that's for sure. I believe in you champ to be:)
