A friend of mine would like to come back in the game.
Do you know when the new free decks will be avalaible? Is it interesting to wait to the release of the extension to come back to have a new meta deck with new cards?
Is there a way to know when was his last connection?
If he had an account on america and europe, he can have the reward in both regions ?
I believe the reward would only be in one region, unless he has separate accounts. Dont know a way to see last login. I would definitely wait until the expansion releases, yes; the returning player decks should be based on the deck recipes, which are updated each expansion.
definitely wait after August 2nd after expansion launches.
Thanks for your answers 
I started playing again and received a bunch of free cards for coming back. I started back in June.
I have gotten back to this game after not playing for 8 months and still I haven’t received any award. How can i fix this ?
