Has anyone tried to do a deck with the Emperor Thaurissan, Brann, Doomcaller effect?

Essentially you get a total of three C'thuns with this.

I'm asking for combo, mulligan and settings.

If not I'm trying to make one now.

It's the first time I'm making a full custom deck with custom mulligan and combo settings.

I'll try to report if it's any good.



_______________Edit

That said is there any way to make the combo trigger only after C'thun's death?
