Nice deck you have there. I like to use the same strategy as well to draw lock the AI with Eternity.
Filtering all the usefull non-Pillar cards in your deck, I was amazed that there were actually only 15 cards.
(6x Dragon, 2x Shield, 2x PA, 3x Eternity, 2x AW)
First, I took out the Procastinations and one Animate Weapon.
They are really not needed. You strategy is to always rewind any creature that hits the field as soon as possible. It doesn't matter whether they are stunned or not, so all the glory of this shield is for naught. Having the Titanium Shields should be plenty.
Also, you will only need one less AW than weapons in your deck, the last one only fills space.
Then I removed the Hourglasses.
If you look at the deck, by removing 6 Hourglasses and the 2 Shields, you can also remove 8 Pillars, so you are already down to 34 cards, which is a reasonable decksize to not play hourglasses.

The problem you are facing now is that you are never able to play all the dragons you are drawing. They are just plain too expensive.
Keeping 2 Dragons should be enough. To still have some damage going, you want to add Graboids, they are cheap and hit just as hard as a Dragon does. Also you could add some Reverse Times, to get a bridge over the time until you get your Eternity up and running. When you have some Reverse Time in your deck, you don't neccesairily need an Eternity in your starting hand. Drawing one half way in your deck should suffice as well, so having 2 of them is enough.
We are down to a modified ultraslim version of your deck:

While this works pretty good vs. AI3, for PvP it would be probably better to go without any dragons at all and focus on the Graboid / RT / EQ combo.
