I used to play it before and then once i had enough cards, i sold them all to buy expensive art supplies. I wanted to get in again but then the deck rewards started to become very low.
Thats when it seemed to me that if i am playing with low level cards then it would take a huge amount of time for me to get anything in return except for fun. And its already less fun with all the bot type of accounts. So gradually i just stopped playing.....
