You seem to have a real aversion to simple concepts...
The antimagic guy will also require a custom power.
PS: I'm really not sure about the balance of Strategist Of The Gods.
Simple is boring. My DM gave me a go-ahead on at least the anti-magic part so that's settled, it's the other things about him.
I don't want to post the wall-of-text I mortared together last night (yet), but he's going to be a technical and mechanical genius, who can put together any mechanical device and understand any electrical system. He was working on secret government projects, including developing shielding against a "new kind of radiation" they had been detecting around certain humans (no words about magic or anything like that). He gets thrown out and loses his security after protesting the experiments on humans and is pretty sure he is under near-constant surveillance at his new work-at-home Navy consulting job. He has a few devices that charge from his body heat, but are ultra sensitive so that if they leave his immediate proximity while holding a charge, they will probably break just from background magic. His aura will extend about 3 feet away from him, but with progress and training, he can pull it onto himself as a thin layer or project it outwards to a very large radius.
The thing that my DM liked, as I said, is that it also will be something the group has to overcome. He can't be affected by healing magic and his reaction to portals and the Nevernever is anyone's guess. Violent magic thrown at him will have to go through the field, and while small spells may dissipate, large ones can still get through and hurt him anyway.
