This is an archetype I made a while ago, uploaded to imgur, then completely forgot about. Inspired by Gaaraofthesand's glitched archetype. Yes, Level 0 isn't a thing, but is a sort of "what if", like his own. Decided to put it straight into experimental cause why not. Dunno if this will get any reviews due to the strange nature, but I hope you enjoy regardless. There's some lore to it, so kudos if you can spot it. CnC?

Interesting, so really, you can only tune the Synchro monsters if there are two level 0 "//" monsters only. It doesn't say that but level 0 doesn't exist except for now.

 

Interesting concept and I like it. It'd be sweet if that added something like this like they did the negative numbers in 5Ds

[JoshForever]

It's a very interesting idea. The ATK and DEF change will vary upon a lot of different factors for each individual card. And as Vectra said, you will only need to level 0 "//" monsters since there is no existing  level 0 except for them.
