One suggestion that could be implemented in the game would be the brewery. it would work like this: it would be a pit fighting style location where you would merge your champions for them to turn into beers, for example every 12 magic affinity uncommon champions would become 1 magic affinity beer and so on for common and rare champions. This would help a lot when leveling your champions in events and to make them much easier at 6 star level. I hope I was understood in my idea and good game to all.
