Common Heroes in AFK Arena are basically just fodder for the Rickety Cart. They can’t be upgraded to anything and they’re very weak.
When you retire them you’ll receive Hero Coins which can be used in the Barracks, and Dust which is used to level up heroes at certain level thresholds.

It’s a bit of a shame that they aren’t more important in the game really, as they do have their own unique looks and skills.
There’s 2 common heroes for each faction. Interestingly there’s no agility heroes for some reason.
