Forum:Necroface deck mill

A quick little question...

on Yu-Gi-Oh WC 2007, i made a necroface deck, and i sometimes use its second effect to mill both decks down, so the opponent loses. However, according to the game, you cannot actually lose the game from that effect. aka, if i have 4 cards left and they also have 4, and necroface is removed from play, neither player loses, but during their turn when they try to draw a card, they do.

Is this a glitch in the game, or is this a legitimate rule?
