One of the main problems with them as a whole is that without a "Labyrinth Wall" monster, they will end up as dead draws for the most part.
The boss card, while it has a rather defensive effect, suffers from a lack of viable means of ATK and direct monster destruction effects, making it near impossible to truly run over an opponent's Field with it.

Neo Labyrinth Wall will be a pain to get out and it still suffers from the weaknesses of Labyrinth Wall Shadow. Ghoul is outright impractical without Labyrinth Wall (and impractical in general out of Fusion) since it bares no good parameters or effect. Worm also suffers from not being that useful unless Labyrinth wall is out, but makes good work if you have Wall out.


Spider and Tank are the only monsters that can be considered stand-alone. Spider's effect to just disappear and reappear allows it to be good manipulation for rank 5 fodder, while Tank can serve as a mini catastor, however, they both still suffer from being heavy dead draws if Labyrinth Wall isn't out...
