You did mention it, but you didn't explain. Aren't concepts and reality two sides of a same coin ? Once reality has been redefined via Concept Manipulation, the new reality basically replaces the previous one, so even if the ability was later nullified, the changes operated would remain (like transmutation : negating the user's ability doesn't turn the victiml back). Meaning a conceptual mutual-nullification would only prevent further alterations, so preparations would naturally be 95% of the first between users (leading to conceptual Gambit Pile-Up situations).
