Forum:Ghostrick Museum vs. Gladiator Beasts

Alright so this is my first time trying to use the forums here but I'm completely stumped about something and hoped you guys would be able to answer.

The simple question: Does Ghostrick Museum prevent Gladiator Beasts from "tagging out"?

The Gladiator Beast's general effect about shuffling themselves back into the deck at the end of the battle phase technically starts before Museum's effect, but Museum's effect activates before Gladiator Beast's. I don't know if a Gladiator Beast can still shuffle itself into the deck when it's flipped into face down defense position. I'm inclined to think that the GB can't shuffle itself into the deck because of this, but I wanted to get more official opinions on the matter before playing that way.
