***TRIALS RESPONSE***I honestly think that the Death version of Spiders/Wings is better for a few reasons. First, poison allows the death deck to get around shields with Poison itself and through Arsenic which the Aether version can not do. Second, Flesh Spiders have a higher HP than Phase Spiders, making them more resistant to CC. Even though it is only a 1 HP difference, Phase Spiders can be killed by all CC except for Thunderstorm. Lastly, Mummies and Bone Dragons, the supporting creatures for the Death deck, cost less and do more damage than Immortals and Phase Dragons, the supporting creatures for the Aether version.
Your deck has a very good build and seems to be very effective at doing its job. There are enough Spiders to stall and your chances of drawing one of them and a Wings is very good, and you have Poisons and Bone Dragons to finish your opponent off. However, there are a few minor problems. The major one is that you seem to have too much quanta. 9 Pillars and 5 Pends is a little much, seeing as the only high-cost cards you have are Bone Dragons, and those are used as an end-of-the-game attacker to finish off your opponent when you already have enough quanta to afford them. I would suggest taking 1 Pillar and 1 Pend or 2 Pillars and 1 Pend out, depending on what you decide to put in.
There are a bunch of different things you can put into the deck even if you only have 2 cards to replace. The first option is to add more Poisons. In my opinion, Death decks can not have enough poison. You could either add 2 more Poisons or add 1 Poison and 1 Arsenic. I know you said you didn't have one, but when you get one, I think it will be very valuable to this deck. The second option you could go for is CC. Air and Death both have good CC cards that are relatively cheap. Tossing in 2-3 Shockwaves or Plagues can help when you don't have enough Spiders to Web the flying creatures or when you are dealing with creatures with Momentum or ones with abilities such as Devour and Infection. The third option you have is to go for more damage via more creatures. This can be done by adding more Bone Dragons or Mummies to the deck.
When making these changes, keep in mind that it is ok if you add an extra card or two to the deck. In a deck like this in which you will most likely kill your opponent before your shields run out, an extra card or two that can give you an extra boost probably won't hurt your draw too bad. Out of all the changes suggested, I would recommend adding some Poisons and a Shockwave or two. With these changes your deck should look something like this:
