I've now played 428 games with a 57% win rate, with only about 8 draws vs decay, incarnate, elidnis, and seism, but at least 15 for all the rest. Note 1-2% of my losses were due to dumb mistakes like not paying attention to a lapsing shield or shorting myself on Aether with a shard.
Ferox is definitely not over 90% as I've had several times where he had 8 Ferals despite my best rewind efforts, making him impossible due to 200+ healing / turn. 78% in 18 matches for him & same 78% in 18 matches for fire queen, but 100% vs Elidnis due to fewer feral bonds.
Also, even Neptune isn't over 90% as there are many times where he can kill in 5-6 turns so if you don't get a pendulum, you're toast.
In a freak match, I lost to Akebono in 4 turns once too, but I'm 55% vs him in 11 matches.
To improve the deck, swapping a flying weapon for a shard makes many matches winnable as you can completely stop any god without an hourglass given 2 eternities reversing 2 creatures every turn.
