I was thinking more along the lines of sets based on specific comic issues, but those are cool suggestions. As far as group sets go, I'd like to see: Warriors Three with Baldur, Frightful Four, Wrecking Crew, and Guardians of the Galaxy. By the way, why do they limit the Marvel box sets to only four figures? I have the Giant Size X-Men set and it's awesome, but would not work as a four piece set.
