1 epic, 4 GF rares, 8 rares, 4 GF commons, 62 commons, 209 SPS, 7.9k merits, and 373 potions.
Regarding cards, there's no other way to say this: these rewards are garbage! 0 legendaries, 0 GF epics, and a single GF epic. This would be better with Gold chests. These are Champion chests! I didn't even get any Drybone Barbarians among the commons, the only one I haven't maxed out yet. The only good thing is that I was able to max out War Pegasus.
209 SPS is not horrible but it's still nothing special out of 53 Champion chests. I've been getting slightly more on most EOSs. The only good part was the almost 8k merits. I got 4 Gladius packs but didn't get anything special out of them. Getting 373 potions is too many! So many wasted chests. I got more potions than SPS.
