Bolas's Citadel of Zombies (EDH / Commander)

Turtle behind [[Koskun Falls]] and [[Propaganda]]. Additional passive turtle from [[Kasmina, Enigmatic Mentor]]. [[King Macar, the Gold-Cursed]] has synergy with [[Koskun Falls]] as a slower alternative to casting [[Freed From the Real]] on him to exile big threat creatures.

Meanwhile:

[[Liliana, the Last Hope]] + proliferate (have only a few cards for this) + [[Deepglow Skate]] to pull off a single-turn zombie emblem. Alternatively, use [[The Elderspell]] to blast some of my own planeswalkers. [[Deepglow Skate]] also ultimates [[Nicol Bolas, God-Pharaoh]] in a single turn.

Overloaded [[Cyclonic Rift]] + [[Jace's Archivist]] + [[Library of Leng]] + [[Ashiok, Dream Render]] to mill everyone except myself and exile it all. Bonus if [[Ob Nixilis, the Hate-Twisted]] is in play for damage on the Archivist's card draw.

[[Exsanguinate]] to gain life for [[Bolas's Citadel]] casting from my library. Alternatively, [[Saheeli, Sublime Artificer]]'s copy ability + [[Aetherflux Reservoir]].

Kill methods:

[[Pontiff of Blight]] or [[Bontu the Glorified]] backed by tokens and a deep mana pool. Not fast enough...

[[Bolas's Citadel]] tap ability fueled by Servo, Thrull, and Zombie tokens. Need to combine this with a sacrifice trigger...

[[The Scarab God]]'s upkeep effect, bolstered by [[Paradox Haze]].

[[Ayara, First of Locthwain]]'s black ETB effect. Need to add [[Phyrexian Altar]] and [[Gravecrawler]] for infinite combo.

[[Torment of Hailfire]] + deep mana pool + [[Ral, Storm Conduit]]. Cast again from graveyard next turn with [[Kess, Dissident Mage]] if necessary. Extra lulz if that next turn is caused by [[Temporal Mastery]].

Most of the rest of the deck is defensive support or card draw. Counterspells, destroy permanents, exile, and sacrifice effects to hopefully remove indestructible problem creatures.

Need to add blue/Dimir creatures with either counterspell abilities or sacrifice abilities. Basically rarely attack with creatures except big monsters that make zombies [[Grave Titan]] or [[Necromaster Dragon]], just use the creature tokens to fuel other actions. Deck shouldn't have many creatures, but needs to generate creature TOKENS quickly and easily. Need [[Gravecrawler]] and [[Phyrexian Altar]] to infinite Ayara for a wincon. Had some plan for [[Ashnod's Altar]] to infinite Thopter tokens but forgot what..... Consider re-adding [[Willbreaker]] to steal creatures, especially since the deck is kinda creature-weak.
