at first, we are going to talk about this one first because we all love free stuff :)!
Every single day, there is a chance to get free 200 Gold, 10 Gems, Silver Chest and Gold Chest. On every Sunday, there is a chance to get an Epic card from the shop for free. There is also the Epic Sunday, don't panic.
The card prices are changed a bit.
From now Common Card now costs 100 Gold each. However, it’s consistent. Which means, If you purchase even 100 cards, the last card’s price is still 100 Gold.
The price is not doubled as before.
If you look at the screenshots above there you can see the card stack x2 or x30 you need to buy 30 cards if the stack is x30. This is truly a lot better shop than before since you can max out cards a lot easier. Instead of buy 1-2 cards every day, you can just save up Gold and buy a bunch later.
