I am done with this game 😡

Well, I used to be playing like 3 years ago, I had 1500 trophies and 1 month ago I have started playing again and now I have 4300 trophies. Idk what happenned but from maybe 60 matches I won about 20 matches… I just keep losing, I was 3 matches from next arena and now I am almost at the bottom of arena. This game doesnt give me any enjoyment, just disappointment… I tried many decks but it just doesnt work, everyone has cards which I dont even have unlocked yet.. I have thousands of hours in other games but I have never been so frustrated like now 😀
