Hey there! This is a new hotfix with changes to some network functions in order to increase stability. We have been reported that some people had issues with the connection so this hotfix tries to address that kind of problems. As usual this patches some of the minor bugs that have been reported.
As we said on the community update, we made a lot of changes to some the cards of the game. We understand that some people spent dust creating decks and this change caught them by surprise and on the other hand, we want you to test those new cards. So we want to give you 3 extra reward chests of 3000 Gold/Shards to everyone as compensation that will help you experience new builds with all the changes that we implemented!
As always thanks for your feedback, support and comprehension.
