Is There a Difference Between Epic and Steel Heart?

The best op games encourage a kind of team work and group play. You can take your actions in orders that you determine best as your team, instead of being forced to go round robin o clockwise around a table or something like that. And the epics will buff steel heart and make the things that he does harder to fight against. It's all just controlled by what's on the board, and you know where the different levels are at for the epics and for steel heart.
