Let's look at possible strengths and weaknesses:
+
able to play all his offensive cards in below 20 turns
resistant to otyughs and similar hp based CC
resistant to quantum denial (a lot of pillars and draws them quickly)
slowing him down requires both reusable permanent destruction and strong CC (eg. lobo)
-
maximum offensive power of 12*7 + 4 = 88 (kill or antimatter a few nymphs and a simple procrastination/dusk mantle/permafrost + 6 SoG and he can do nothing)
gravity shield!!!
no PC and very limited CC, and as we all know FGs of this kind are generally easy with most anti-FG decks
generally reliability on a single card (golden nymph) for offense so anything that counters that (antimatter, gravity shield) beats him much easier than FGs with many damage sources
Anything else that needs adding to the list?
I guess a FG like this could be added at some point if people keep complaining about FGs getting harder, and would join the Osiris, Neptune and other easier FGs, but I guess the deck might need some tweaking to make it more dangerous. Maybe add Dune Scorpions and Unstoppables?
And a Turtle Shield would be nice, as it slows down rainbow decks unless they PC it.
Flying Eternities is also a good idea... rewind FTW
EDIT:
I almost forgot, a very big "-"
Annoying card drawing animations
