Clash Royale review: Unbalanced matchmaking

The matchmaking in this game is unfair. I'm not sure if this will be sent to anyone who has control over this, but I would be happy if u even showed this to someone who did. Whenever a new deal comes out, I am forced to stop playing the game for the day due to the amount of players spending money on the game to advance. I understand this is how the game works, but I cannot play a game that is constantly unfair. A person with a good sense of strategy and skill in the game could not beat another person without skill in the game, just because they payed 5 dollars. There are also two cards that seem to be the most unfair, and as soon as I see them, I know I am going to lose. The megaknight, and the firecracker. Players who usually use this card seem to also be very rude and have very high level cards. In the arena I am in, it is more than half of players that fit this description. I am completely unmotivated to even continue playing this game. That doesn't mean I am more motivated to spend money. I don't want to be the person that puts money into this game and gets unfair wins against people who just want to escape their day with a quick game against a fair opponent. I am sending this here because I cannot find anywhere to put feedback into a game. If someone high up sees this, you should probably ask for feedback from your players to make the game more enjoyable and playable. Here is mine. Remove the megaknight and fire cracker and incorporate card levels into the matchmaking algorithm. It would make this game so much better and fair. I have been playing this game since I was a kid. The addition of these cards and the unfair matchmaking has ruined it.
