If the stats are the same as the previous free set of banners as the devs said, then the max stats when enchanted are as follows: Red: 3% Attack & 1.5% Defense Blue: 1.5% Attack & 3% Defense Green: 2.25% Attack & Defense
Devs stated that they were the spy counterparts in a subsequent reply to their own thread... Yes, devs should just repost it in their original, but hey, they are just happy people play......
