i found with this new update, i am able to go from bronze 1 to gold 3. Last season I rented 2 great cards to boost my CP by 70k for 4 days.. spending like 1k dec.
this time I got to gold in 5 days meaning I had to spend 1500 dec on GF lord anus LOL
so we shall see if its worth the reward but its definitely stressful up here... I have mostly level 1 summoners but a few gold ones and a couple level 2. Still fun but dang maybe its worth renting cards?
hmmmmmmm
I would say take it easier and aim for the Silver league. Buy some cards, they are cheap.. esp. inprint reward cards (which are good).
i have enough personal power to get to silver 2 myself. 40k CP.
i just always surpass it and get to gold so once I do, I rent a gold card till end of season.
