Humans has long been a major tribal archetype deck in Standard in which most of its components today was provided by the set Shadows over Innistrad. Mono White has been the most stable build but recently I have thought of having Green as its second color to open my access to a few spells which I also used in my Black Green Energy decks, specifically Blossoming Defense and the sideboard plan.

Here below is version one of the Green White Humans:

4 Thraben Inspector
4 Town Gossipmonger/Incited Rabble

Spells
