Commander: Land Dispute is a custom set I work on from time to time, it is a mono-colour tribal commander set wherein lands matter. I am posting this to get feedback as well as to get suggestion for the 5th (white) tribe. I do not want underwhelming tribes or tribes that have been done to death.
As you can see all the tribes I have chosen are either basically non-existent or really lacking in much needed "Umph" you know? it would be helpful is a unique machanic is given to the tribe as well such as the Djinn's and "Fetter" or the Nightmares and "Dreamstride" (see my set)
anyway, suggestions are welcome and here is a link to the set so far https://mtgcardsmith.com/user/LexiFjor
