I must say, while the deck would look fine at first glance, it is rather large.
I think the main issue you are having with the deck is unreliable draws. With larger decks comes the possibility even if it is the slightest, that in your case, you may draw 3 Anubis, in a deck where getting 24
will not be easy.
I suggest that you cut it down to 30 cards into something like this:
4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4vd 4vj 4vj 4vj 4vj 5c2 5c2 5f6 5f6 5f6 5f8 5ie 5ie 5if 5ol 5rn 5up 5up 61t 61t
As your deck seems to focus on creature control, splashing in some permanent control, you may want to invest in spreading your quanta use a little more, as I notice that you have not used
,
,
, or
. Purchasing and including cards such as Boneyard, Otyugh, Plate Armor, and Blessing may increase your chances of winning through using all the quanta that Quantum Pillars produce.
A deck like the following uses its quanta a bit better and would provide you a better chance of not only winning, but of winning with an Elemental Mastery:
4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4vd 4vj 4vj 4vj 4vj 52n 55r 58t 5c2 5c6 5f6 5f6 5f8 5ie 5if 5lf 5ol 5rn 5up 5up 61t 61t
Sincerely,
