I've been trying to find a home for Deadly Tyrant. This feels like a good fit! Ancient Bauble and Shadowlands Tyrant trigger Katra like a social justice warrior at a state college. Add deadly to the tyrant and he's a fucking assassin! All while buffing the rest of your board pre-combat... and post combat...
Along with the old Ayan on turn 3, Katra on 4... or play defensively like I usually do and wait until you can trigger a bauble once or twice as Katra lands... Depends on how aggressive your opponent is. The nightfall cards really help this deck draw smoothly... I'm not 100% sold on Encroaching Darkness, but hey, this deck is all about living the dream. And it can definitely help push some games over the top.
