My guess is he just finished watching Goldmember and has decided to turn the sanctum into a giant magnet to pull in midas 22 the heart of magic.

As for someone asking why there is a bunch of giant cattleblasters over the double line. All I can think of is its a really crappy attempt at distance perspective, you have the double line, and then an inner line of defenders. The inner line looks bigger because they are closer maybe? Or he has created a force of giant cattleblasters to add to the mix of normal snuggly faced cb's and the meat puppet cb's that are attached to giant snuggle chunks.
