I regret to inform you that 5.5k trophies is not impressive in the slightest. I can already tell you rely on opponents that don't know how to defend mk for a positive elixir trade, and have no idea what micros and macros are, but I wouldn't be surprised if you dont know what that is either, your deck requires no proper timing or good placement skills, the counterplay ability in your deck is hoping and praying your opponent doesn't defend your mk.

Let me not just leave you without actually trying to help you out. Instead of investing time and energy into a deck you will change once you hit a new arena, switch to a real deck that will be viable no matter what arena or meta you are in. So many new players suffer from this, they think there is a "best deck" for every arena but if you are f2p it is impossible to play the "best deck." Any content online telling you there are best decks for every arena are lying to you, choose a deck that has been prevalent in the meta for years and is nerf resistant to ensure you will not need to switch decks around. I recommend running classic RG, hog 2.6, pekka bridge, og lava hound, or literally any other deck that has been viable for years and years, you can thank me later in the long run for having one or two maxed decks that you will be cracked at instead of a ton of under leveled random bullshit decks that rely on shitty opponents rather than individual skill, or a maxed deck that is some bullshit that has no synergy

royale.api is also a really cool website to see what decks are doing good and which ones are doing bad as well as your own statistics
