My personal take on Pharaoh decks in general is that the decks themselves have a minimum critical mass, that is to say the deck itself must have the bulk to actually provide the whole setup and stall until it can achieve as such, and i opine this value to be at 40 cards. While I understand that you are rather into the research of 30-card anti FGs, you are dreadfully short of time quanta (which is another reason to take more cards--stockpile more) especially if you were forced into a situation where you had to generate a scarab and rewind one card to avoid deckout. No harm testing, but I don't think this deck is going anywhere.
This deck isn't meant to be a Pharaoh-first deck, and it falls in line with your assessment of Pharoahs. I see the one Pharaoh in this deck as a replacement for the one Firefly Queen previously in this deck, with a little more flexibility because of Scarabs. That is to say, the Pharoah should be played during the endgame.
As I continue to play this deck, I find that I need to have an early shield up (preferably Permafrost, or Jade Shield for FGs with permanent control) and then go for Aflatoxin. Depending on the FG, then I need to choose whether to go for early creature or permanent control with the Mind Flayers. However, I agree that a 30-card deck may not be optimal size for this deck.
I really haven't run into a situation where I am short of Time Quanta -- but again, I believe it's because I lose early before I ever need them. If I can establish control of the board with Shield+Aflatoxin+Mind Flayers, I haven't used any Time Quanta at all. And if I get that 1 Time Tower out early (without it being destroyed) I easily have 25-30 Time Quanta to start with before I begin playing the Pharoah.
I estimate that I am around a 30% win rate, which for a starting deck with my play style, isn't bad. Since I primarily play against FGs, I have a losing record (currently at 1110 wins, 1387 losses). But I do have a nice set of upped cards to work with.
I (may) need to play with the size of the deck some more -- I've thought about putting an Hourglass or two in, but I think that would really drain the Time Quanta.
