Satan is a being of the Neverworld rather than the Everworld. Hence, he is a creature of fantasy rather than reality, and can only be affected by thing imbued with fantasy. You said "reality" gets sucked in, which he is not. From what you have explained though, he'd get affected anyway.

However, BFR won't work. Satan can't exist outside hell, and if he leaves it, Alaya puts him back where he should be.
