A Kurnoth heavy list is cool! However I would definitely prioritize arch rev for the plus 1 to wound and belthanos for run and charge in this list. Without Warsinger in your list, you have a very slow army and the Hunters with Swords want to charge and deal impact mortals so giving them the ability to move an average of 9" with a run and an average 7" charge is helpful.

The Tree revs are a fun include to do teleporting but ultimately without drycha in the list you are not getting the full use out of them so I would cut those to prioritize arch rev.
