The thing about that other deck is, precogs. After you play a SNova then essentially all those Precogs become speedthroughs of the deck. Although being completely honest I prefer Mono-time Pharaoh for this kind of deck. ((Mono-Time Pharaoh simply being 14 Time Towers, 4 Time Pendulums, 6 SoR, 6 Pharaoh, Gravity Mark. Its honestly 'very' efficient at what it does.))
Also, unless you're talking about reverse time itself, what CC are you talking about that can be rushed out to greet a 8 hp pharaoh and kill it in a couple turns? That heavy CC usually requires a Domin deck, which has a low level of damage output itself so its not going to rush you. And scarabs become very heavy defensively once you get 6+ up. Plus, you 'defense' is inbuilt into the scarabs in the form of devour.
Also, if you want some true stats to prove your claim, just play 50 matches against FG's and record your wins and losses.
