Basilisk Blood is very important (I would switch to
pillars and an
mark at this point), then move to supernovas and changing to an
mark.
Once you up supernovas but not sundials you have a ~90% to draw 1
pillar (if still using 4 and assuming a mulligan chance.) Also a supernova in the first 9/10 cards, which is when you can first cast if off the mark, is ~90/93%. Given this fact, I might test hourglass 1 and only with unupped dials for a possible chance to improve draws. Although 3 towers gives only a ~69% chance to draw in the first 7 cards with mulligan factored. I will try to get this put together after trials have concluded.
To use the hourglass it should be upped. I would note that between electrum hourglass and upped sundials I feel the drawing power "smooths" out what looks like a "bad draw." I hope my tests will elaborate if using unupped sundials is a viable option. In any case hourglass shouldn't be used if you rely on your time quanta to play unupped sundials.
Using twin universe obvious reduces the quanta you need to produce, while coupled with aether towers ensures you will almost never lose a game do to lack of
quanta.
The next move I would make is the voodoo dolls as you get an increase of 4 hp. Gravity pull to gravity force should never be a problem once you get supernova but there is slight possibility of helping against some of the more difficult match ups, like Decay or Chaos Lord or Dream Catcher (thanks majofa for being a fg guru
)
As a final note, I often prefer a cloak mod to increase my odds against rewind or mutating gods. Also it can save your hourglass or sundial when you may really need it against pc heavy fgs. As with gravity pull this isn't a huge boon upped, but against some 1 quanta saved may give you the edge you need against devs/discord.
