Fiendish Chain

Casius is tribute summoned.
I activate fiendish chain.
He chains Mystical Space Typhoon.
Does Mystical space typhoon stop fiendish chain from negating casius?
As mystical typhoon destroys, not negates will fiendish chain negate casius effect?

Continuous Trap cards like Fiendish Chain needs to remain face-up on the field in order to resolve properly. Mystical Space Typhoon doesn't need to negate it, it's effect will simply disappear if it wasn't face-up on the field during resolution.

ch1: Caius
ch2: Fiendish Chain
ch3: MST

chain resolves
ch3: Mystical Space Typhoon destroys Fiendish Chain
ch2: Fiendish Chain's effect disappears
ch1: Caius banishes its target
