Viridian Zealot is another card to consider for Torpor Orb removal, but is significantly weaker than Caustic Caterpillar, Reclamation Sage, or even Nature's Claim.
I have two suggestions: Manglehorn in for Viridian Corrupter and Inkmoth Nexus in for a land. Manglehorn is slightly easier to cast than Viridian Corrupter and continues to be effective past its enter-the-battlefield effect. Inkmoth Nexus flies, dodges almost as much removal as Lumbering Falls, and is easier to activate than Falls. I have had good results with these cards, but if you are using the Corrupter for infect more often than not, these changes may not be desirable. What do you think about this?
I have been testing Crop Rotation for tutor-access to Gaea's Cradle and Inkmoth Nexus. It feels lackluster, often ending up as a dead card in hand because it's not a creature and therefore cannot advance this deck's board state without an existing presence. I have my sights set on testing Traverse the Ulvenwald in its place, but I may swap that slot for a creature instead.
You mention that a major weakness of this deck is Torpor Orb. Have you considered Caustic Caterpillar? It's more green-intensive than Reclamation Sage when cast and activated on the same turn, but easier to search for with Green Sun's Zenith, Chord of Calling, Eldritch Evolution and Yisan, the Wanderer Bard, and can be played on turn one to threaten fast mana.
