The most powerful living human psyker against a named Necron lord is like putting your most well trained in MMA toddler against a hungry bear. But since Mephie is technically from the Imperium, lore demands he doesn't lose.

Yeah, Necrons call that getting a snack from the kitchen
I ain't no 'cron polisher but if we're going to go on lore-accuracy, Necron tech mogs anything the Imperium can muster short of the Emperor getting fully rejuvenated, and that's what it would take for them to present anything the Necrons would take seriously. And they laugh at every other race's excuses for warpcraft, except for the Eldar.
