What's up with that Chaos War set?
If you are asking that question, then please allow me to use this thread to answer it for you.
Chaos War is the newest Marvel Heroclix set. It is/will be sold in 3 different ways.
1. Chaos War Micro-Set (aka Gravity Feed aka Countertop Display)

On June 28th, the Chaos War Micro-Set released. It contains single-figure blind booster packs with a total of 10 different figures available.
The 10 possible figures are:
#201 Iron Man
#202 Thor
#203 Captain America
#204 Space Phantom
#205 The Vision
#206 Masque
#207 Ms. Marvel
#208 Ultron
#209 Spider-Woman
#210 Wonder Man
The Chaos War Micro-Set is currently available at Merlyn's.
2. Chaos War Fast Forces

This is a six-figure pack with 6 specific, pre-determined figs. It comes out on Wednesday, July 11th.
The figures include:
cwff001 Iron Man
cwff002 Thor
cwff003 Captain America
cwff004 Wasp
cwff005 Mockingbird
cwff006 Scarlet Witch

The Captain America, Thor, and Iron Man figures from the Chaos War Fast Forces set include the
Stand Together! special ability that shows up on their final click and reads as follows:
"Stand Together! When turning the dial, if there is an adjacent friendly figure with the Avengers keyword and the same or higher point value and this click is revealed due to damage taken from an opponent's attack, stop turning the dial."
Functionally, this can, in the right circumstances, give these iconic Avengers one last heroic stand when the odds are against them.
3. Chaos War (regular set)
Also out on July 11th will be the regular 5-figure blind booster packs. This will be the full set featuring characters chosen from the full list of 53 regular figures (or from the small list of chases, which may be include as many as 8 different figures. More on that below.)

Don't forget: Wednesday, July 11th on the Chaos War release day we are running a single-booster, play-with-what-you-get draft like we do for every big release. A week and a day later, on Thursday July 19th, we have our Infinity Gauntlet Month 7 event, a sealed two-booster game playing for the Grandmaster LE figure.
