I find it quite hard to judge given the focused nature of the AOJs, but I find a lot of these cards overpowered.

Removing cards from the graveyard isn't a huge sacrifice to make to draw 2 cards, or destroy monsters on the field.

Crippling Invader I find OP to the point of banable, due to the near-impossibility of getting rid of it.

I quite like Grappling Spy (although the name is rubbish) and Neo Clauslus though, although I think Spy should be only revived from Graveyard instead of Special Summoned from hand, and Neo Clauslus effect activated if an AOJ is destroyed by battle by, or by the effect of, a LIGHT monster.
