change mark, time is good
remove 3 bonds - 2 is enough
remove 3-4 boneyards (i prefer only one, but i usually have one other shield in deck)
remove 2 elves - 2 is enough as well.
remove 1 oty - 3 is quite enough
remove arsenic (when you get some other weapon, that is)
remove 1 lava golem (or possibly both, it has no synergies)
remove FFQ - 1 is quite enough , usually when you get one out the quantums are not a problem anymore
remove 1 PU - it's utility but well, you can most probably play without (so maybe remove both)
remove 6 pillars - manaflood isn't good either
that leaves us with 39-41 cards
add 2 sundials - more draw
add some novas (4-6) - manafix, should give a fast start, cant be destroyed. So i prefer play them and pillars, not pillars only
add rain of fire - mass removal is quite useful in many places.
add 3-4 golden hourglasses - more draw
49-53 cards.
what you miss is eternity, to prevent milling self to death (go and farm top50 for that, foyle is very good opponent for that
). Pulverizer is nice to have too. Comes from same place
If you cant get opponent in top50 for some reason change browser (changed mine from firefox to chrome, and it started working )
Also protect artifact and animate weapon might be good ideas ( anubis + animated weapon , other weapon just protected)
The idea behind it is to have as small cardcount as possible (but cant exactly to put all needed combos into 30) to make key card probability higher. Key cards are those that give you card advantage (sundial/hourglass), also it's a control deck, so stalling is good too (sundial, phase shield)
