The Avengers Vs The JLA

Who wins?
No prep...
No B.F.R...

Blue Marvel
Dr.Strange
Thor

Vs

Superman
G.L Hal
Wonder Woman

The fight can go either way, depending who faces who and if its Classic Strange.

If the Justice League goes up against Classic Strange, they'll be hard pressed. Diana would be the best match for him and even then they are going to have a hard problem if Hal or Clark take too long taking out their opponents.

Team Thor wins.

Thor tips the fight by being matched up with Blunder Woman.

Although the glass canon fight could also be a tipper too... I'll go with Thor though.

Marvel team is too powerful. A little more versatile as well.
