I tried this and I'd have to say it truly is funny little deck to use. I'm not convinced though that this has better FG win% than Hope/RoL (on 1.24 I had 50% wins from 400 games), and my short testing says this certainly is slower than it.
I'm now trying couple of ideas how to make this work better:
1) Pharaoh! Time+Gravity already in original build, + Eternity or two ain't enough to keep critters in leash forever.
2) Gravity Pendulums + Mark of Time.
3 biggest change)
Entropy! Dune S. + Unstoppable is a great card combo, but Dune S. + Chaos Power is pretty much as good. If you add Antimatter to the mix, you can also pass shields. The idea I had is that Entropy also has Butterfly Effect, Pandemonium, Dissipation Field, and Maxwell... while Gravity has Otyugh, Armagio, and eh um mm nothing else really.
Entropy/Time could look something like this
