Historic Jund Citadel by Will Erker
Prosperous Innkeeper is the perfect fit for a Jund Sacrifice deck that is trying to abuse Bolas’s Citadel. This version of Jund Citadel from Will Erker uses a lot of the new cards from Adventures in the Forgotten Realms that create Treasures, but the best thing about Innkeeper is that it gives you extra life to keep going with Citadel.
The goal of this deck is to play out a bunch of creatures, most of which either get you ahead of mana or create some value when you sacrifice something. Once you get to six mana with the help of your Treasures and cards like Priest of Forgotten Gods, you cast Bolas’s Citadel. Then, you can start chaining cards from the top of your library, hopefully killing your opponent on the spot thanks to multiple Blood Artist and Mayhem Devil triggers. Combined with the scry from Woe Strider, you can usually keep going even after hitting a few lands on the top of your deck.
From the new cards, Shambling Ghast seems a little weak to me, but it does only cost one mana and replaces itself, so it’s passable. If it created the Treasure when it entered the battlefield instead of dying, I would be a lot more excited about it, although at that point it would probably be too good.
Skullport Merchant was my MVP in the Forgotten Realms prerelease and can definitely help dig deeper into your deck here as well. Deadly Dispute also seems a little on the weaker side to me, mostly because this is a four-of Collected Company deck, so I would try to maximize the number of creatures instead.
In the sideboard, Thoughtseize might be better than Inquisition of Kozilek, especially now that Jeskai decks with cards like Torrential Gearhulk, Mizzix’s Mastery and Teferi, Hero of Dominaria are popular, though I understand not wanting to pay the two life in a deck built around Bolas’s Citadel.
