The strategy involved is so basic that the game becomes 100% luck. Either you run into a dragon without divine edge, or you have divine edge and get to 20+ without seeing one.
Easy game that gets painfully repetitive- quickest way to get a great team is to save your money for the end of the season to transfer players- then use any leftover to upgrade at the start of the next season. Always make sure you have like 15k to buy new players at the end of the season.
