Classic Golgari midrange is actually good again ?

Golgari midrange driving a big Wagon. This is first version on Wagon deck and its performing suprisingly good already. In Golgari colors we get smooth painless mana and all tools we need. If deck would be upgrade the biggest upgrade via cards would be adding blue. Sultai colors would give Riddlers, Winternight and Awaken of honored dead, but mana would be much worse. Lets see where this decks is going in future. Deck kind of was there but reality fractures Vraska take deck on hole new level.
