And the deck itself:
6rn 6rn 6rn 6rn 6rn 6rn 744 744 74a 7n2 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q0 7q3 7q3 7q5 7q5 7q5 7q5 7q7 7q7 7q8 7q8 7qc 7qd 80h 80h 80h
I'll suggest down the deck size to 31 cards,
remove all hourglass (-4),
-3 Time Tower,
-1 Gravity Tower,
-1 Anubis,
-1 Turtle Shield,
-1 SoG,
+1 Eternity,
+1 Animate Weapon
In fact Dune+Unstoppable is not a must, since Pharaoh can do the job and also prevent deck out. What Dune does is faster the damage and ignore shields.
Well, of course I based it on my experience with a Pharaoh deck, so the defensive part and the pharaoh-offensive part are similar, and only the gravity and Dune Scorpion part and some tweaks distinguish it from the standard Pharaoh approach I've used.
As for the suggestions, hourglasses are extremely useful both for the drawing power and for permanent control (protecting SoGs from deflags).
2 Gravity Towers was useful against Decay, Dark Matter and seems to fuel Scarabs better than one.
As for Anubises, yes, one might be enough, especially if it's only mark-powered, but it's nice to have it played early.
As for Turtle Shields, I'd sooner add another one, I've lost too many times due to not drawing one early enough.
+ Eternity + Animate Weapon... sonuds like a possible change, though increasing the deck size. It's a kind of both defensive and offensive card, so should not disrupt the defensive capabilities of the deck.
