The ZNoxx combo has to be a better, earlier example of a mutant circuit.
Or even the Storm/Polaris(+Havok/Cyclops) electromagnet move that threw Krakoa into space, but I guess reminding people of that would just undermine the entire Krakoan basis...
Len Wein even calls it a circuit.... but whatever. Maneuver 7, aka the fastball special, will take the credit even being a very rudimentary combination.
