Hey, first of all, If you're using a time mark I see no reason to add the time pendulums. Although you may say that it's to avoid having only towers and preventing earthquakes and such, If that's the case then okei.
- I'll take out an antimatter, I think you have 3 because of the 3 DS so you could get pass the shields eventually, but 2 DS dealing 2 neurotoxic p/turn is enough.
- Maybe just 1 eternity, I use it only when I'm in danger of decking out and with 50 cards that is very unlikely... (if you take 1 Eternity then remove the animate weapon)
- Take out the 2 dimenssion shield
- Take out 1 or 2 SoG's
- Maybe 1 or 2 Electrum Hour
And having set aside those cards you should check how many towers you need later.
Maybe if you added some supernovas (perhaps entropy mark?) you could incorporate some momentum into the deck without having to worry about shields, and with the extra mana also add in some death scorpios to max the poison dealt, that way you could even remove a few pillars.
And with all the extra quanta given by some supernovas you could use some epinephrin to increase the pois dmg dealt p/turn, thus speeding your deck. But that is another story.
Hope this helps
