"white night dragon-mirror force"

this monster can be destroyed when is alone on the field by mirror force?(cause mirror destroys many monsters but in that case destroys the one which eff says that it cannot be destroyed by eff that designates this monster!)
that happened while i was playing with ducky and both stuck!

A monsters effect such as above over powers Mirror Force. Mirror Force may destroy everything, but if a card can't be destroyed then MF has nothign over it.

Mirror force does not "Target". White Night Dragon can be destroyed by its effect.

Targets:
Dimensional Prison
Brain Control


Doesn't Target:
Smashing Ground
Mirror Force
Bottomless Trap Hole
Lightning Vortex


The amount of cards that would be affected has nothing to do about weather or not its targeted.
