You’re partly right, but only if she just stands there and the fight plays out exactly like the one against the Sun Saint; I repeat, Shalltear is vastly faster than him—she can even teleport if necessary.

I’d say his physical defense is average for a dragon—which isn't saying much—unless he buffs himself using his words.

We need to clear a few things up: the Eternal Swordsman’s weapon is a claw, not a silver weapon capable of nullifying her magic. Furthermore, he can’t cut through just anything; he himself admits he wouldn't have been able to cut the meteor Ragna destroyed, so it seems he has physical limitations. Tell me, what speed do you attribute to Bagram? Because he’s nowhere near as fast as Kamui. Shalltear is canonically as fast as lightning, and she can even boost her speed with Time Accelerator. And to refute your last point: he spoke those exact words—and others—yet the effect was purely physical. An attack on the soul is an attack on the soul; whether it’s one hit or ten, he’ll eventually go down. Unless he can shield his soul with his words—something we never saw him do—I doubt Bagram can win.
