hey there,
I think that your Deck choice is pretty interesting and I do like the Topic of your Deck.
But i would make a lot of changes.
You need more Stuff, that allows your Defenders to Attack, you need tutors, to find the enchantments, wich alow your defenders to attack.
You also need ramp, or the other Players will be to far ahead (speaking of Natures Lore, or
Cultivate...).
Last but not least, you need at least 33 Lands, I recomned for this deck about 37. So you have to many spells in your Deck.
Cute the 2 Gylphs and cut all Defenders that are "Vanilla" creatures, or creatures wich do almost nothing.
Better play some Recursion, or your Enchantments will get destroyed and you will never ever Attack.
Last but not Least, Doran has the great opprtunity, to play -X/-x Massremoval, wich wont kill your own board. We have Black suns Zenith,
Languish and
Toxic Deluge.
PS: Maybe consider a Treefolk Subtheme
Kind regards Hawjik
