Why Darkness?
-Russian Dolls hide others... and I think all the hide stuff is for Darkness xD
-In Darkness you already have a doll (Voodoo Doll) so, unless you think you should have only one kind of card (like scorpions) by elements, It could fit IMO.
-I don't know which other one could fit better?
It doesn't Duplicate/Make an illusion/Summon from a parallel universe other Dolls...
Unless you use a catapult IT DOESN'T FLY XD
Dolls never dies^^
It fit better for golems... Russian dolls are wooden figures most of the time.
Just NO.
It can burn easily but it's not the point.
NO WAY.
It's not a living creature, it's dolls.
Well ok, this one could fit IMO, when you seperate you put a doll to the light in some way. Furthermore, according to wikipedia, there is Church-themed nesting dolls which fit with angels.
It isn't a Deja Vu like, it doesn't duplicate. Separate dolls take times but not that much...
No.
As it is dolls I have thought "Other" is the best but with super nova it's OP.
