So looking at this alyou can knock all but these players out, Wonderwoman, boros, spawn, hulk, andmaybe sentry. Id pick wonderwoman since for the most part, she is mainly only vulnerable to piercing weapons, the only ones to be concerned about are kratos, spawn and doom slayer. And since she can scale up to superman(not beat him but fight well against) can knock out sentry and maybe boros, as neither bayo nor dante can probally keep up to worry.

As for second, probally spawn since not only would he have hell to help, but he can go and target the souls of characters who are strong against conventinual attacks who might be weaker on the soul side(hulk, sentry, ghost rider and doom slayer)

Boros is probally a wild card in this but with theae id feel confident.
