Our forum profiles can pick a favourite Attribute... it's a start...
Would like adding the Types (both card types and monster types) but phone would make it hard...

Funny... Charlie's fan cards lack an "Aether" type... but "Quintessence Elemental" is an "Elemental" type (which is fanon)...
Also a Fusion Monster, I think... not sure on Attribute... maybe LIGHT...?
