Weaker than what's posted:
1. You have no protection. At all.
2. Even if you had dissipation shields, you still wouldn't have the entropy quanta to support it.
(
Emphasis added.)
ian didn't design his deck to sustain Dissipation Shield in the first place, which makes his Entropy requirements less stringent and lets him summon Nymphs more reliably and readily because he can get away with Pends instead of Pillars.
In fact, the Nymphs are the more central part to your plan (Diss Shields needs some control to keep the shield going without drawing outrageous amounts of Entropy, lest swarms of hostile creatures will run all over you and your collapsed Shield, and that's where the Nymphs come) that if I would change the mark of your deck to Water first and foremost before pondering the quanta balance. Waiting well into the eighth turn to summon your first creature (assuming unupped Nymph's Tears and Mark of Water) when your deck is creature-centric is never a good thing, but that's about the worst case if you've got your Tears before that eighth turn. With Mark of Entropy, if you're particularly unlucky with your Water Pillar draws, you are leaving him to EM you simply because you couldn't summon any offenses at all into the field.
