my personal opinion:
Cut Urban Utopia and Abundant Growth and replace them for Wild Growth and Overgrowth. This will help with the extra mana. Cultivate/Kodama's Reach still work well in an enchantress deck. and indeed, you use too much tapped lands. try using, aside from basics, more dual color lands that can enter untapped, such as Temple Garden, Canopy Vista, Fortified Village and Sunpetal Grove. The first two also work really well with Krosan Verge.
But hitting the right second landdrop is essential with Sythis. The sooner you can activate the voltron of her, the better!

Hi,

I know you have a lot of draw power, but i would add like 3 more lands to be honest.
Card draw is amazing, but you need mana for it. If you cannot cast your commander on turn 2 it you will fall behind quite quickly. And yes, more basics.
You only play 2 colours, and of of them is in green .

Maybe for removal (2 all-stars for my enchantress decks): Seal of Primordium + Seal of Cleansing.

Just my 2cents.

Good luck!

you should remove more of the unbasic lands and replace them with basic. i tried your deck and the mana base is almost unplayable
