Hello,
I want to share my impressions and opinion about the new card system after one day of testing / looking.
First of all: There are some bugs that need to be fixed. I guess everyone knows
Second: Nevertheless of the existing bugs, I really really like the new system! I hope, that you don't need the 5 Star System except for making a card available in other decks, because if you pay diamonds your card still remains at the same star level, but is available in other decks.
But if you don't have any disadvantage when paying/maxing with diamonds, I really like and enjoy this system and it really meets my expectations!
Greetings
