MARVEL Mystic Mayhem puts a lot of focus on team-building, and it's even more important if you're a free-to-play player.
There are different modes, and a team good in one might struggle in another. Over the last five days, I have been pretty lucky to get some of the best units currently available. I also managed to test out a couple of other accounts to check out all the 3-stars currently in the game. This guide will help you make the best possible squads for every available mode, and I have focused on the builds for F2P players, because why not!
