Pre-Crisis villain team Vs Marvel Earth

For this fight, Marvel earth has Sentry, Classic Dr. Strange, Reed Richards, etc... This villain team is trying to take over earth. It includes the big 7:

Ultraman
Mordru
Mongul
Lex Luthor
Black Adam
Professor Zoom
Mr. Mind

Jean Grey solos?

I don't think she can solo. Mordru himself is a good battle, though he will have his hands full with Strange.

Etc...?Potentially reed solos if prep is allowed.
