Forum:Burden of the Mighty Vs Dark Synchros (i know the DS's are anime only right now)

Ok, now i know that the Dark Synchros are currently Anime Only, but IF they were ever to be made, what are your thoughts on them versus Burden of the Mighty. BotM reads: "Each face-up monster your opponent controls loses 100 ATK x its own Level." and Dark Synchros have negative levels.

So do you think that their level will be increased or decreased?
