WW would basically gut, scale and fillet Namor and serve him with lemon and a side of fries.
Classic Thor and CM would stalemate each other. But Classic Thor would win in the long run IMO.
Basically it would come down to Surfer vs WW and the one who wins will help out. And we all know who'd win here.
I think Team 1 6/10 in a 1v1 fight.
I doubt this'd go 1v1 tho. In 3v3 fights we have to consider that each team will use teamwork to win.
WW and CM would speedblitz and Thor and the SS will be the one to take the brunt of the hit. SS will prolly use his powers to amp Thor (making him pretty deadly), Thor would use his hammer to absorb GL's energy, etc.
Still would give a small majority to team 1. SS ability to enhance other ppl's physical characteristics and Thor's ability to absorb energy through Mjolnir gives them a slight advantage vs team 2.
Why do we keep thinking that this would be a 1v1 fight?
It's a team fight.
Surfer Amps Thor to well beyond CM levels, Thor absorbs most of the GL energy thru mjolnir and, with his cosmically amped strength, smashes thru the weakened shield in one or two blows. They take a several hits from WW and CM but they can take it (they're two of the most durable characters here). But GL goes down hard.
Namor grabs his pompoms and cheers in the sidelines.
2v2 Thor, SS vs CM and WW is a hard fought win but still a win for Team 1.
Team 2 is obviously more powerful than Team 1 but it's how you use your powers in conjuction with your teammates is what will make you win. Though Team 2 could go smash Team 1 with a decent speed blitz.
It's iffy, but i give team 1 at least 5/10 to 6/10 (very slight majority) in this.
