Okay so trying to think up a deck that might work, and this is what I've come up with as a possibility or at least to inspire someone better than I.
Rare Metalmorph = Negates spells that target the machine monster... So Soul Exchange and Enemy Controller become worthless.
Abyssal Designator to get rid of Man-Eater Bug
Gravity Axe to prevent switching defense mode...
Card Exchange to try steal the Kuribohs and Enemy Controller...
Pot of Benevolence/Gravedigger Ghouls to remove Necrofear..
Twisters for Ectoplasm (Not sure if this would still have an effect on Electro with Rare Metalmorph equipped.
Anyways, hopefully someone can come up with better ideas.
I do not recommend trying this, I was just looking at cards that could have some viability, I also have no idea how the AI plays, ie will he use spells even if Rare metalmorph is equipped? I don't know....
