[small-ish necro? -- hopefully this is an excusable case relating to tasks I am tackling for Phase 1 of 10th Trials of Death]
I do concur with dragonsdemense regarding the deck size - it is conceivable you lock-down your opponent's damage but end up unable to deal a killing blow. Adding one card is not a large hit to the reliability of the deck but it means you win 100% of the time in stalemates against the way more common 30-card decks.
Regarding the EM's, I might suggest not "playing with your food" any more than a few turns to achieve that EM. This is especially true in Bronze and AI4 where the per-game reward that gets doubled is not usually worth having to go 5+ more turns of just "holding off on your killshot". Pursuant to that, unless you expect to hit a lot of Poison from an opponent you could drop the Purifies which is double bonus so you can add another Trident (cripples chance opponent fields a CHAIN of Dimensional Shields) and not be tempted to wait long periods of turns to EM lower-level opponents.
If you are not in possession of two more Squid to field (1 in place of the 2nd removed Purify and 1 to increase deck size from 30 to 31 total cards) then I would suggest removing the loner Octopus and replacing with a third shield.
For more than just tweaks and nips of change, here is another idea:
Replace the Shields and Purifies with 4x Elite Antlion (not sure if you own these... but in case you do --) and sub out the Octopus with another Trident (or Poseidon). Add 1x Stone Pillar (or Tower if you have it) and replace an Earth Pendulum unupgraded with 1x Stone Pillar (or Tower if you have it).
This would result in the following deck (cool fact - summon the Antlion and get it burrowed ASAP... while burrowed it gains +2|+2 which
double again when you unburrow!)

which could result in some match conclusions like:
[One final suggestion is to consider perhaps a +1 Stone Skin if you find yourself constantly having plenty of CC early game but needing a heal late game from a difficult Poisoning opponent... I know I had the Purifies removed but hey, I can slightly contradict in a constructively critical review right?
