Notes & Combos
I did not make Zeus once. I made Underworld Goddess twice.
I experimented with various other extra deck cards like Zenmaioh and Durendal but Zenamioh always felt too slow for when I actually needed it and the Droll/Durendal combo never came up for me. Vallon was useful, but N.As.H Knight would probably be just as good if not better. The issue for me is extra deck space was tight.
I did not find having 2 Link-2 Galateas useful very often over occasionally having the option to use Link-3 Longirsu for removal or recycling.
W:P is actually very nice in this deck. Most of the time you end on Enlilgirsu + I:P if you start with Girsu uninterrupted. On the opponent's turn you can W:P using I:P and Galatea-I and then have a negate on board as well as access to S:P, Longirsu, or Underworld Goddess.
Going second is rough. A good hand can bait out or play around many hand traps, but a bad hand folds instantly. I would consider including Triple Tactics Talent.
