I got some questions:
1) By which turn do you have an Eternity out in average? (The odds of drawing it are mediocre I guess)?
2) I don't have a third Nymph so I wonder what you would put instead.
I consider Turtle Shield since I can destroy it with SoFo in case it gets stolen or an EH.
Not sure if the Pharaoh's cost is too high to really be helpful.
3) Has this by now been tried in one of the Arenas? If yes, where did it work best?
1) i cant really give you any precise numbers on that, but on my testings i didnt have trouble getting one out, wheter by luck or the fact that i could also have a nymph out racing through the deck to get the combo out faster
2) Anubis or pharaoh can work quite well by giving you safety in your combos or by increasing damage and CC options. A shield can work too if you want to put it, maybe to give you more time/quanta for when you dont have a SoRed eternity and you spend a lot of quanta RTing creatures
3)I dont know of anyone with 3 nymphs using/testing my deck in any arenas, but i think i've seen a similar one being used in gold arena with solid results
