Nice win streak!

You should think about renting some cheap power during season. You are missing 3k power to get to Bronze 1. Try to rent cards with >300CP/DEC. this would end up in around 10DEC/day, but you will get 5-7 DEC per win instead of 1.5 in Bronze 1 at your current rating.

and on top of that your chances are higher to get a card and less potions in the daily quest reward.
