I think Weather Wizard can take the team on his on. He can conjure up a storm/hurricane, but that's just me of course. Also, mirror master is pretty tricky because he can jump from mirror to mirror or shiny objects (or something like that).
I see people vote for Rogues. Im not too familliar with most of the team 2 chars so not going to argue. But just wanted to point out that most of the T1 characters were recently upgraded.
Scorpion got a suit that protects him from all kinds of physical attacks.
Sandman can make sandclones.
Electro is a living electricuty.
And its speculated that after his rebirth Kraven can only be killed by Spider-man.
So might be a decent fight.

True, but there is no way to beat MM if he's in his dimension. Mysterio instantly gets taken out. The only member i'm worried about is Electro. Not sure how the Rogues will take him out.
Some matches are pretty close, but when you add Weather Wizard or Mirror Master that's where things get interesting. MM constructs/mirrors have been able to incase Hal Jordan.
