This is the Superjj N’Zoth Anyfin Paladin Deck w Ivory Knight he was playing on ladder. It has a lot of the same cards as the Trump Anyfin deck but adds N’Zoth as an extra win condition. N’Zoth is worth its cost in paladin just for a Tirion, anything else is a bonus.
You often need just one more turn for another Anyfin Can Happen bomb, so it makes sense to bring N’Zoth to the deck, I think it makes it stronger overall.
