If I may ask you also used only rented cards? On how many Summoners did you focus?@eddiespino thank you for your comment and encouragement!
It seems to me that playing with only one is not very optimal. I'm easy to counter, I have little chance to get rewards in Daily Focus, and I don't learn much about the meta.
I wonder if I should spend more time on "cheap" Bronze to learn how 2-3 decks perform, instead of trying to climb to Silver to soon. I would really appreciate your opinion on this.
