Helvault

[Cllzzrd]

Can {helvault} tap and exile itself to bring back all the cards exiled with it? You would pay the costs, which are 1 mana, tap it, and exile it, and then since it would leave the battlefield doesn't it and everything else come back?

It's not a creature.  If you were to exile it, it would not be in your GY

I misread it! I thought it was target non land permenant. My bad!

Well 
Technically you could run it with {Tezzeret, Agent of Bolas}, and make {Helvault} a creature î,,

EDIT: It has to hit the GY, my bad.
