Achievements and trophies are just the beginning of the fun in Clash Royale. There is also the possibility to compete with other players, so you can see how they are doing and if they are going to the same places as you. It is also possible to get a good idea of the current meta, which is the set of cards that are being played in the game. By playing and analyzing the cards you can see how the meta is evolving and what cards are going up in popularity.

Now you can get even more information from your game. Deck Bandit is a free app that will allow you to import your current decks, so you can check out the meta and see how the game is evolving.
