You're confusing MDCs with Alternate Universe Copies. MDCs are [i]extremely[/i] rare even with infinite universes, because it requires certain criteria that almost nothing is able to meet all of. Dark really only had them because that's one of the traits of the AT. 
I really probably should make a page about that on the wiki, huh?

That would be preferable. Mention it in the Dimensions section of the Existence page, if you will.
