Horrible plot devices. I'm interested in seeing how they will turn out when released though, they need to keep some interaction wich other.

I'm more interested in how they'll be censored.

It will probably end up as something as generic as "Black Doom" and "White Doom". As for their effects, they will most likely have nothing to do with each other whatsoever because, honestly, if they did they would be terrible. Then again, if the plot device is removed, they become nearly free Dark Holes for a close game.

If they both summoned from your Extra Deck it would work, otherwise it's unreliable. Even so, I'd rather they do something else, or that the anime makes its own 13 and 31.
