Hi, nice deck!
To answer "
Commune with the Gods OR
Lead the Stampede OR
Winding Way..." I'd like to share my opinion:
Since you're playing landfall you will tend to need either more creature or more lands to trigger them during games.
To that purpose
Winding Way will be your best option since you can choose either.
Commune will not be as useful after you have a
Nylea's Presence, and
Lead the Stampede is great but won't get you lands if you need more landfall triggers rather than creatures.
Hopefully that helps you.
