FIX THE MATCHMAKING!!!!!!!!!!!!!!

I dont understand how can you be winning 10 matches or what and then in ONE second you start losing 10 matches. How does that even work? Whats the point of playing the game if you have a winning streak and then you lose all the trophies from it !!!? Please explain. Also why is that I am being matched with someone higher than me, do you want me to be losing? They of course have higher level cards than me. I really dont understand.
