@inx1127 I bought some common cards because it's cheap but I don't buy any rare and legendary card yet I just rented out any card which I want for one day, currently my ranking is above 800 hundred in the league for this season
Focus on cards abilities then try to understand which card works for you during battle and get this card on rent minimum for one day
Oh right, yeah i am studying each cards and the abilities, testing for effective combos...thank you bro!
