Mirran+Crusaders and Hero of Bladehold, but now it’s all Delver+of+Secrets, which I hope to play against every round since Liliana and Black Sun’s Zenith are so good against them.”
Jon has adopted several answers to the heavy presence of hexproof creatures in the format like Invisible+Stalker and Geist+of+Saint+Traft. Between Liliana of the Veil, Black Sun’s Zenith and Curse of Death’s Hold, this version of U/B is capable of quickly neutralizing opposing armies before grinding them out with a slim suite a finishers.
Nephalia+Drownyard does a lot of work for Jon’s deck. Working with Adam Prosak, they developed a plan that involved milling themselves to at least 20 cards in the graveyard, fueling Visions+of+Beyond and netting a ton of flashback effects. A powered-up Visions+of+Beyond off Snapcaster+Mage is huge and can easily seal a game in Jon’s favor. And really, what’s better than making 13 zombies?
