Still, if you're winning 37.5% of the time against the easier gods, that's pretty good for an unupped FG deck, especially one without any rares.
The unupped has aa smaller easy list than the upped though
Chaos Lord (sometimes, depending on mutations and if he draws any of his 4 PC cards)
Destiny (sometimes, depending on mutations and Fate Eggs)
Elidnis (mind the TUs, but if you go OTK with an unprotected spectre, you'll be fine)
Ferox (Too rushy, you won't win)
Fire Queen
Incarnate
Miracle
Morte (The early rush isn't too much issue, but combined with the poison, you're dead)
Neptune
Paradox (TU will kill you, due to the fact it's not OTK)
Scorpio (see morte)
Seism (you're too reliant on pendulums in this build, you can't win)
There's also the fact that you often use you're dim shields too early, and die 1-2 turns before OTK is possible. Just go LS/AM. You win more.
