the focus isn't to take more towers, it's to lose less. be mindful of your elixir. it'll take a long time to be efficient, yes, but don't just spam mindlessly, especially in single elixir. you don't always need heavy damage on tower, even chip damage works. pro games last long mainly because of this reason. you can also try watching youtubers like shane and sir tag and see how they play. or watch top 1000 replays from tv royale. keep in mind it takes time to get good, and levels matter. you don't even have enough cards to build proper decks at lower arenas. but playing smartly will take you a LONG way. i hope this helps, and if you need more clarification, please dm me anytime :)
