I do play a little using a silver account. Cracking those chests can be a buzz, and if you 100% rent it won't happen. I am after potions more than anything.., as I won't crack packs unless I have them.
The lower leagues are still bot infested and it's hard to win unless you have OP'd cards. Higher up.. that's where the skill comes in.
I'd have to work my way back up through the leagues and I can't be arsed for now.
