Mainly 1 and 3 but they can take 2 as well. Imagine Storm with CIS off. Now what you've imagined her doing will actually happen.
Havok and his energy blasts has dropped Juggernaut, gave Hulk fits, and sent Gladiator flying. His output is top tier. Iceman would destroy. Everyone on that team can be affected by below 0 temperature. Everyone. Archangel throwing poison blades, Cable doing his telepathy thing...Colossus being a heavy brick. Namor being a heavy brick. Yes, they take the majority.
I don't care about the outcome, but can nobody, REALLY, figure out what the God of Thunder could do to Iceman? Or does young Thor not have his weather powers either? They aren't linked to Mjolnir, after all.
Assuming this isn't God Cable, everyone's kinda ignoring the other two for team one as well. I think minus TP being an insta-win, they'd thin the field to about 3-on-3 in a hurry. Sure, Namor's a hoss, and Havok can bring some pain. But this is still the 3's match to lose.
He has weather powers, but can't Bobby come back from literally nothing? I don't really read x-men, but every thread I see involving Iceman everyone describes his as some kind of psionic being that inhabits ice forms or some crap. But again I don't know much about the post 90's X-Men.

Other than Iceman, Unvinciblewith PIS/CIS off would speed blitz everyone faster than they can form a thought. like Omni Man did to the Gaurdians of the World. They even had a flash like character called the Red Blur, who move so fast that girlfriend had no clue he was saving people while talking to his gorlfriend, and she had no clue he was moving at all.
So Mark blitzes everyone, but again Iceman is a bit of a lame foe that only Psychics can really beat him.

I'm pretty sure, say, dispersing most of him into space via a worldstorm would suffice for the purposes of this thread. Certainly it would count as a KO long enough to decide the fight by other means.
