What if someone else tries to hold the master sword?

[Lozjam]

technically that scene originally took place when the master sword was still the goddess sword and the dragons trails were just a vision i think it didnt actually happen.

I don't think a vision has the capacity to kill you.
They are remnants taken from Links Memories, yes. But they still hold every single characteristic they have when they fought. So while it may not be Ghirahim himself, this is proof that someone else can weild the master sword. This is also further proven by Link's master sword being stolen in SS.

yes every characteristic which means the master sword has the characteristics of the master sword. Lets just say this doesn't count because it technically isn't really happening
