The problem with the
verdurous gearhulk, is that as awesome as it is, it still doesn't help with flying or reach. There are too many fliers in the meta to ignore from the sideboard. I cut the sideboard Jace, and one
Kopala, Warden of Waves to side in
Nissa, Genesis Mage and a flier (I've been experimenting with
Angler Drake, mostly to get two ETB effects from cards like
Vineshaper Mystic and
Rishkar, Peema Renegade). Remember the Planeswalker rules have changed - it now used the legendary rule: if you control two legendary cards with the same NAME, one of them has to go to the graveyard. So both
Nissa, Genesis Mage and
Nissa, Steward of Elements can be on the board at the same time, and their interaction is insane. You can get her out super fast with Rishkar.
The other thing I did was to cut two of the
Unclaimed Territory and a
Botanical Sanctum in favour of running three
Evolving Wilds, Mana is not an issue in this deck at all, and the
Evolving Wilds thins the deck. Mind you, I use early permission to control the early tempo so that I can suddenly explode my board - keeping Essence Scatters, and
Supreme Will mana up (Our stuff is small at first and generally needs more than one creature/enchantment on the field to make things big enough to survive early cheap removal.)
