as in a battle royal?

i'm stuffed if i know but it would be one hell of a thing to witness......at a serious distance, like from orbit might be safe enough :)

as much as i dislike them i'd have to say the ultramrines probably have the best chance to survive, simply because pre-heresey they were the largest legion by some margin.
