How about designating at least four of your five "remaining" slots to lands? I think this deck wants to run at least 38. Suggestions:
Krosan Verge,
Zagoth Triome,
Indatha Triome,
Murmuring Bosk. Oh, and the new
Nesting Grounds of course. They basically made it for this deck.
And you're in green, so run
Farseek,
Rampant Growth and
Nature's Lore instead of the Talismans. A nice enchantment tutor that fits the theme of the deck is
Lost Auramancers. Concerning counter removers,
Spinal Parasite is a bit clunky, but there's just so many that we have to take what we get. With your flickering subtheme,
Quarry Hauler could be worthwhile as well.
If you want to strengthen the enchantment theme, consider
Bounty of the Luxa. By removing the counter or not, you can modify quite well if you want to ramp this turn or rather draw an additional card (you just can't ramp twice in a row).
