Would Strionic Resonator be useful for double triggers?

Feed the Swarm, Infernal Grasp and Pongify could be possible cuts for the suggested removal spells.

Cut a swamp for Geier Reach Sanitarium

I might be wrong about this but delve seems counter productive to the strategy. Cut Treasure Cruise and Dig Through Time for the much needed Entomb and Frantic Search.

Entomb, Frantic Search, Geier Reach Sanitarium, Vanishing Verse, Anguished Unmaking, Vindicate

You aren't bad at this. You took a lackluster commander and made an original concept and a deck that flows!

Preacher weak body but it's a strong blue effect in white that fits the decks theme.

Tangle Wire it's always fun making stax effects one sided.

Throne of the God-Pharaoh value.

Cryptic Gateway might work in this list.

False Floor is this the home it was looking for!?

Dust Bowl anytime I see a deck with a lot of basics I recommend this. So good in the late game.

Dope concept! Clean and tight list too.

Cavern of Souls, Pyre of Heroes, Harsh Mercy, Kindred Boon, Radiant Destiny, Mirror Entity some tribal cards for your consideration.

Flawless Maneuver you are running a lot of the usual suspects "good stuff" this might be worth a spot.

I have an Abzan life gain deck. These are some cards from it that might be worth a spot in your Esper strategy.

Essence Pulse, Kaya's Wrath, Kambal, Consul of Allocation, Divine Offering, Serene Offering, Shambling Vent, Aetherflux Reservoir, Alhammarret's Archive, Blighted Steppe

I see a theme of untapping lands... where's the Krosan Restorer?

Running Dryad Arbor and Green Sun's Zenith... where's the Natural Order?

Skyshroud Poacher might be useful.

I was the first person to comment on this list... still no Hall of Gemstone? One of the quintessential green control card! It is version of Blood Moon/Back to Basics. Brutalizes fancy mana pools/multi color.

Petrograd you were ahead the curve! It took 2 years but Marionette Master finally spiked because of the juicy treasure token synergy.

Descendants' Path tribal tricks.

Hall of Gemstone brutal in

Hum of the Radix since your deck doesn't utilize many.

Mutavault seems useful.

Skyshroud Poacher seems really useful.

Konda's Banner to finish out the playset of artifact anthem effects.

Huge fan of Lands.dec especially in EDH.

I like your straightforward concept but this glass cannon needs a playset or 2 of support cards to streamline your strategy. Stuff like Gamble, Mystical Tutor, Personal Tutor, Muddle the Mixture, Drift of Phantasms, Ring of Three Wishes

Land's Edge #2 incase Seismic Assault has been dealt with.

Otawara, Soaring City much needed removal that doesn't mess up your strategy.

Dust Bowl is incredible with basic lands.

Sunstone convert to snow covered lands and this card alone would grant you real time via green/white Fog tech.

If you were to use every suggestion I just made your land percentage would be 87% which still wipes out a table of 4.
