For new players, upgrading the cards in your Clash Royale deck can be a daunting task. Not only do you have to save up enough gold, but you also need to collect enough of each card to access the upgrade. As you keep playing, you'll naturally climb up the Trophy Road, unlocking newer arenas while you progress. But if your deck doesn't keep up with the levels, you'll have a hard time securing wins later on in the game.
