I'm using a slightly different variant:
6rs 6rs 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6u2 6u2 6u2 6u2 6u2 6u2 6u7 6u7 6u7 6u7 6u7 6u7 6ve 6ve 6ve 6ve 7te 7te 7te 7te 7te 7te
For comparison's sake, as kirchj33 requests in the OP I'm not skipping anything until the moment it becomes absolutely impossible. Divine Glory is literally impossible from the get go, so he gets skipped right away. Ferox, Fire Queen, and Osiris are probably impossible in practice, but I'm sticking with those fights anyhow until either their healing outstrips my maximum damage output/Osiris gets a trebuchet out. Elidnis, Lionheart, and Dream Catcher are all terrible for this deck but potentially beatable (I'm on the fence about Jezebel, because she will steal your towers and prioritize them for Nymph's Tears and wind up with tons of antimatter nymphs.) This is still generally a pretty inefficient measure of grinding capability since there's a fair number of gods that really need to be skipped, but creating a good objective measure of a deck's grinding abilities is problematic in general; besides, it's fairly easy to take a full set of data and estimate the FGei with certain skips.
Eternal Phoenix is actually very doable; chaos power + antimatter on an early dragon gives you a fighting chance. You should be able to manage ~15-20%--still something that should be skipped in actual grinding, though. Seism is even easier, as your total quanta usage is actually pretty small and shriekers are great targets for you.
