Next tournament at my venue is 600 points, no figure under 100 points. I was playing around with the idea of playing the New Avengers and sumpled across this combo:
SR Sentry 197
SI Iron Man 188
V FF Power Man 109
V SIn Spider-Man 106
600 points on the nose, with lots of attack and support power.

I'd play it. It looks like fun. Only figure I don't have is Power Man.

You could try this too. Not alot of air mobility though...

Build
188 SI021 Iron Man
197 SI059 The Sentry
136 SI058 Power Man and Iron Fist
78 WS007 Spider-Man

599

The Spider-Man doesn't meet the requirements (no click under 100 points.)

You are correct Sir!

Then try:

Build
188 SI021 Iron Man
197 SI059 The Sentry
111 AV051 Spider-Man
100 AV045 Thunderstrike
596

Unfortunately I don't have Iron Spider-Man.
Not really important though since the tournament was yesterday. Since another guy showed up with a Sentry/Iron Man team I decided to field a Kree force instead: Noh-Varr, Ronan the Accuser, V Photon and SI Captain Mar-Vell. Went 2-1 and got second place (missed first place with 5 points...)
