I really appreciate the discussion here.
First off, I'm not sure if I could make my point when I said this in chat, but you can effectively protect your Flying Eternity by playing it and then play a bunch of fractaled creatures, as Anubis and I think also GotP get targeted over it. Only the heaviest CC gods (Rainbow, Osiris, Neptune, Destiny) can hope to tear through an army of Anubs. That's why I generally think a second Quint isn't necessary.
Generally, my advise to all the modifications is: Keep in mind that want to minimize the number of cards that don't help you in the early game. Helpful are (roughly in that order) Hourglass, Phase Shield, Towers & Pends, SoG, Eternity. The others (AW, Anubis, GotP, TU, Quint, Fractal) are just going to clog your hand. The main goal of the deck is to survive and draw your deck. In that deck there is a package of cards that allow you to win the endgame against any (non-Decay, non-Jezebel) god. This package should be as small as possible. Here's a couple possible packages:
- 2 AW, 1 Anubis, 2 TU, 1 Quint, 1 Fractal (7 cards): The one I used in my pre 1.27 deck. This package WORKS, so any package that has more cards than this is pretty unexciting. It's disadvantage is that it's pretty slow as it has no GotP.
-2 AW, 1 Anubis, 1 GotP, 1 TU, 1 Quint, 1 Fractal (7 cards): I think this would work just as fine as you have a faster clock with GotP and might not need to go over the top with Eternity as hard. Also it's faster than the first
-1 AW, 1 Anubis, 1 GotP, 1 TU, 1 Quint, 1 Fractal (6 cards): If you're a little more greedy you could try this. The problem is that you can get max 3 Eternities, which can get awkward against certain gods with healing or more than double draw (Paradox, Fire Queen). Also because of the only one AW/Quint, it will take a long time before you can make a Flying Quinted Eternity, which can randomly win you a lot of games otherwise.
- 2 AW, 1 GotP, 1 TU, 2 Quint , 1 Fractal (7 cards): I like the idea that Anubis might not be needed anymore. Against the heavy CC gods you can probably also jog through with just a quinted GotP + one-shot Fractal, and it has 2 of both AW and Quint meaning it can get flying Eternity faster.
