Around a month ago i started play the game and always finished in the bronze tier, but this season i learned how rent cards. Thanks to that, I managed to reach gold 2!
And here is what I got for the end of season reward!
I know ... it was awful. But it could be worse, right !?
In this season i will try manage to stay in the gold tier and hope to get better rewards.
I started around a month ago too and I just hit silver. I couldn't advance further because of the card power limit. But as you mentioned card renting might be a good solution to that and I'm heavily considering it!
Rent is very cheap and really worth it.
