Jund was always the fair deck in Legacy, mostly because Deathrite Shaman, Liliana of the Veil, and Punishing Fire were a pretty good combination. With Treasure Cruise banned, I expect the color black to make a triumphant return, although who's saying we need green in our Jund deck?
Goblin Rabblemaster is a powerful card that has slowly been transitioning into Legacy, and it's even better in decks with Deathrite Shaman. Equipment tends to go well with it as well, so that's where Stoneforge Mystic comes in. Lingering Souls is also great with equipment, and works with Liliana of the Veil, so overall, white has a lot to offer this sort of deck.
Alright, so maybe since we have those Grove of the Burnwillows and Deathrite Shamans, we can afford to get some Abrupt Decays in the deck. You'd want the green source for Deathrite Shaman anyway, so it's kind of a freeroll.
