One of these three things would happen:
1. Madara uses Almighty Push to send Naruto, Sasuke, and their "Sword of SoloKings" flying.
2. They hit Madara, just for him to instantly heal himself and brush it away.
3. Madara uses Universal Pull to attract the Sword of SoloKings into himself; Naruto and Sasuke then sh*t their pants.
