This is a budget Izoni, Thousand-Eyed deck where I used all of the cards from the Golgari Guild kit and the remaining cards used are all under 1$ each. This is a typical Golgari dredge shell and I went for quantity over quality with some of my creatures as I'm looking to setup either the Mortal Combat win or a hefty Spider Spawning. This should be a good introduction for newer players who want to get an idea of what playing a Golgari deck feels like.

I would say the best route to go with Izoni post upgrades would be an Aristocrats style deck. You should definitely look into Dictate of Erebos and Grave Pact to repeatedly edict your opponents out of the game. The Traditional core of Viscera Seer, Carrion Feeder, Blood Artist, Falkenrath Noble, and perhaps Poison-Tip Archer to drain your opponents would be good includes. I can’t stress enough how good Life from the Loam would be as my next upgrade, the card is such a valuable engine in pretty much any green deck, and for the purposes of Izoni you fuel your graveyard with dredge and can rebuy cycle lands to cantrip into your game-ending spells. If an upgraded list is something you’d like to see I can put something up on tappedout to give you some ideas.
