Define bad, even now they are playable despite then current game being really fucking toxic towards it.

Biggest issue is that most decks are purely body spam for generics meaning that decks in general tend to lack proper identity. Aside DDD and Endymion since those have whole support from get go. Konami don't help by printing whatever generic extender over proper archetype support.

At least Solfa got support on DOOD, making it a whole different deck and far less reliant on whatever generic.
