I actually remember getting stats pretty close to zse's when I tried this deck a while back. Of course the big thing to note is that this deck was released and tested during 1.26 whereas now it's 1.27 and new FGs have been released in addition to an AI buff. I would expect it to have caused a bit of a decrease in the win rate, but not to the extent where its win percentage would drop by more than 10%.
QFT. Can't say how much that intelligence boost on FGs did on win-rates, since I haven't used this deck that much lately. I'll do a short test-run when I have the time for it.
Besides, while Jezebel is nearly impossible and Hecate is strong, Serket is cakewalk, and Akebono is too easy.
Jezebel: 8 Steals can cause problems, but quite possible if you can lure it to use those for something less important.
Hecate: 4 Steals. Easy if you can keep Eternity (or Crusader with Eternity) on table.
Serket: No problems if not rushed super-fast. Eternity and walls are enough.
Akebono: Without Eternity you may lose, with Eternity it's almost impossible for you to lose.
