User blog comment:Water Dragon Slayer/DREAM BATTLE CHRONICLES: SECOND MATCH!/@comment-7418318-20130723191212

After all this discussion about why it can't be done, let's try anyway.

Mavis and Zeref stand before each other.

Zeref launches a wave of death at Mavis, but since she's dead it doesn't affect her.

Mavis then tries to punch Zeref, but being a ghost her hand phases through Zeref.

The match ends in a draw because they can't hurt each other :P
