As title. Please advise if there exists one mod like this. Thanks!

intriguing suggestion, if you were, by any chance motivated to have a particular hero available for selection at the start, there used to be a way to enforce that by erasing all other heroes from the hero pool.

Yea.. I am looking for a set of heroes not sure if that's possible.. 

But I don't want to push too hard to have all them in the beginning, might be overpowered or suck all my dust prod in the beginning, can't tell...
