Hi,
I really like the idea of selling uncommons for 25 crystals.
This is an opportunity for one or the other to get a grip on that uncommon that you like but never get.
I wonder how big the offer is and if it is repeated after some time? Since everyone has to sleep once in a while it would be sad to miss the offer you want.
Regards!
Just use uncommons that aren’t complete trash next time please.
Well, unfortunately most cards in this game are more or less trash. 
I hope that these offers are generated randomly so that any uncommon has a chance to be offered.
Edit: I just saw that it is Grove Rumbler again… So, it’s just a small amount of cards that are offered in a circle (let’s see what comes next) or it is totally random and just bad luck (for me at least ^^).
they posted up in news and announcements what cards are available this time round, and how the whole thing works
Okay, so nothing for me this time.
But I still like the idea.
But I hope they keep it up and offer new uncommons every 48h.
I hate it, especially since there’s no confirmation button. I accidentally clicked it and now I’m out 25 crystals for a crappy uncommon.
Sorry to hear that but the offer is not the problem. There should be a confirmation button before ANY purchase! No matter if crystals or money.
Edit: If you have some endurance, you can write the support and try to get your 25 crystals back, if the was a duplicate.
