I'll just give you my first impressions of your iteration without providing a real alternative, but here goes:
I don't like the split of Pillars and Pendulums. This is a general thing. If you go with an Entropy Mark I prefer Time Pendulums and vice versa. Then you add Time Marks OR Entropy Pillars / Pends to get the right balance. In your case there are 10 Entropy Towers and 10 Time Towers. That would get changed into 20 Time Pendulums. Since it's upped and playing the card gives you exclusively Time quanta minor re-balancing is required, though. It is also advisable to see if it runs better with an Entropy or Time Mark. Pick whichever you need later. I'd try an Entropy Mark.
Quanta balance is always an issue and needs addressing my next point.
Usually you'd try to use Quintessence with those Nymphs but Anubis + SoR is also CC resistant. Yet, I am not convinced it's worth the investment. SoR unquestionably helps Anubis but you'd expect this kind of deck has enough Entropy quanta to repeatedly cast AM so you wouldn't need SoR on your Nymphs.
An easy way to win against decks without PC is Eternity, definitely a great addition to this deck. As you already remarked this deck does not win by faster damage. Just healing and not decking out is slow but wins games. A lack of damage only matters if the opponent destroys/steals your Eternity and you don't lose to damage. So you have 23 turns to do enough damage 32 damage per turn does suffice, CC is mostly irrelevant.
The important part is to get to the point where you heal more than you get damaged. This will get more difficult against smart players, though. And personally I would not want to play this deck against AI. Naturally, Shields are a great defensive mechanism, use them. Turtle and Tower Shield come to mind.
Also, this is a deck you do not need to cling to 30 cards. I would try not to get above 32, especially with Eternity, but adding few tech cards while maintaining a good draw chance for your core cards is key.
