I know of at least four mavs. Three were one-offs and the other was a vintage mav(ocean mav). I have two of them. I'll try to get pics up later.
TT had a few of these, and chose to match the price ($100) that S7 used because of the small figure issue. There was next to no profit margin on these boxes... I got lucky and got a one-off Nougaki in my box...but also got a crappo Ankoron...every US distro box seemed to only have the small figures. I love surprises, and I've tracked down some amazing pieces from the MixBoxes since they dropped...but there was an enormous amount of Anks in these things.
