Lucky me today as I got the Water Quest and it helped me win a number of battles in a row that set me up for promotion to Gold II. The rewards weren't as good as yesterday but not every day is Sunday.
It is interesting that all the cards I got were flying cards. I have upgraded all of them already and am far away from upgrading to a level where it makes a difference. Also, the summoner limits would make them pointless.
There were some surprising wins along the way like this one above. I thought the reflect ability would have ruined me with so many magic attack creatures but the enrage on the Kraken is what rescued me. It is crazy since one card practically cleared out the entire deck.
