|Once you master the game, you transcend auto-fights and come up with the best team composition for every battle!|
As with most game crafting, the idea of metagaming is to use apply knowledge gained outside of the game to receive an advantage. For example, for every update that comes out, certain aspects or mechanics of a hero might give them an unexpected advantage in play styles used commonly in dungeon raids. As more people use those heroes, play styles and team composition are shifted to adopt the new changes. In other words, the meta changes and winning teams become more populated with these. Of course, it does not end there. As more people adopt the winning team, there are strategies constantly being developed to counter those teams. Once the counter-attack receives greater popularity, the meta will change once again. This process does not change over a few days though, as it may take up to months at some times.
