So my venue is running this format next Monday:

400 points
100 point max per figure - No figs with a (total) value over 100 points
Must play matched pairs of 'same name on their dial" figs
Named figs cannot change or be replaced during play
Highlander rule is suspended for this event
No limit to number of paired fig sets
Can play Two or Four (i.e Spiderman), but not three

Any suggestions? I have access to nearly everything from Captain America onward.

125 FFCW001 Iron Man
5 ATA064 Secret Avengers
60 CW001 Captain America
5 ATA064 Secret Avengers
110 CW024 Iron Man
5 ATA064 Secret Avengers
83 CA040 Captain America
5 ATA064 Secret Avengers
398

And an Avengers theme.

That looks like an awesome team, but the format is 100 points per figure, including ATAs.

Oh! Reading comprehension fail. Sorry.

2x FF Supergirl 200
2x DKR Harvey Dent 120
2x AIM Agent 76
Scorpio Key 4

FF Supergirls with Willpower, 2PCs and 2 Perplexes? That should do.

I'd pair up Avengers Movie characters with their comics counterparts. Captain America, Hawkeye, Black Widow and Tony Stark are all useable.

SM Composite Superman x2 - 160
CW Nitro x2 - 82
GG GF Drax x2 - 150

392pts Brute themed

Use 2 Composite Superman to TK 2 Drax for double charges, or 2 Nitros for double Explode and Reform. That's double the fun. Hehe. The 2 Composite Supermen aren't push overs too, with both Superman and Batman TAs, they're stealthy and stealth busters at the same time.
