Pre-Crisis Madness Vs Marvel's Elite

Mr. Mind gathers some of the toughest beings from the Pre-Crisis era. His team is:

Mr. Mind
Alexander Luthor
Validus
Mordru
Composite Superman
Zha-Vam
Blackstaar
Ultraman
Mr. Atom
Black Adam

Vs

Mephisto
Thanos
Count Nefaria
8th Day Juggernaut
Morg W/WOL
Kurse
Overlord
Xorr The Jewel God
Mangog
Maestro

And for those who are not sure about Black Adam, back then, he was truly invulnerable. Captain Marvel could hit him with Superman type blows for hours and Adam wouldn't feel a thing. Same with Marvel.

the god jewel was said to be more powerful than galactus

Mephisto retcons the DC'ers.

Not going to be that easy. Mordru would negate Meph.
