I got:

M10A012 Iron Man
ASM032 Moon Knight
CL1-05 Iron Fist
ASM008 Doctor Druid
FFCW003 Captain America

all with the Secret Avengers ATA, and the M'Kraan Crystal Sliver as my relic, and AVB004 "Frenchie" DuChamp to tie it all up.

I do need some advice though. I'm wondering if I should swap out my FFCW Cap and Frenchie for ha040 Captain America and an Amadeus Cho bystander from Mutations and Monsters. I figure with the FFCW, I have that Leadership ability that allows me to clear a token from somebody 125 points or fewer on a 6, that's virtually everyone; but if I put in ha040 Cap, then I can hit anybody regardless of outdoor blocking terrain or characters, AND I get an outwit with Amadeus Cho. What do you guys think I should do?

I actually really really like that FFCW Cap. The combo of 6 range, plus new and improved Quake can keep him pretty safe. I mean HA040 is a great piece, no doubt, but I like the ability to charge in and knock people around a bit.

You could try the original lineup:
Build
130 FI005 Valkyrie
99 CA031 Steve Rogers
75 CW015 Ant-Man
45 CW022 Sharon Carter
109 ASM032 Moon Knight
5 ATA064 Secret Avengers x 5
483

I think that looks like a bunch of fun. So much so I'm going to go pick up Steve Rogers and Moon Knight so I can run it! You can have a side board of various Hank Pym figs for all your support power needs.
