Infinite Mana:
Food Chain + (Eternal Scourge OR  Squee, the Immortal)
+ Walking Ballista = Infinite Target Damage


Good cards to add:
Chandra, Torch of Defiance
1 drop ramp (Elvish Mystic, Llanowar Elves, Wild Growth)
Card draw (Toski, Bearer of Secrets, Tovolar Dire Overlord, Beast Whisperer, Lifecrafter’s Bestiary)
Beastmaster’s Ascension
More removal and board wipes
Cards to cut:
Sarevok’s Tome and Chaos Wand : very slow, there’s better stuff.
Greater Gargadon, Arasta, Dream Pillager, Lovestruck Beast, Managorger Hydra: off-theme or mediocre creatures.
Durnan and Passionate archaeologist: good cards, but not the focus of a Faldorn deck.
Sandwurm Convergence, Journey to the Lost City, and Primeval Bounty: expensive enchantments that don’t do enough.
Some 2-4 cost ramp: adding 1 cost ramp instead will help you cast Faldorn on turn 2. I cut Explore, Nature’s Lore, and Three Visits.
