Just a different (greedier) take on Roshi's mandrake mask deck.
I am missing
Send an Agent and it should be replacing annihilate asap.
I am pretty unsure about the powerbase, but I did feel like hourglasses weren't doing enough and that katra was just overlapping with their role every other game, so I just removed them.
Valiant Guardian's influence is sometimes hard to hit, but with so many grafters (and draw) in the deck and some planning you can just market them in for something else and pull them out later when you can finally play them.
All in all this was one of the most fun I've had with a mask deck in a while and took me barely any effort to get from bronze 3 to master, as I hadn't played in a long time.

The Shiftstoned power calc makes the deck look almost unworkable. I assume you get around it with sheer draw, but how often do you find yourself unable to play Katra, The First Seal? I agree that playing Katra and Arcanum Hourglass in the deck feels redundant, but Hourglass does a little bit of fixing that can make you able to play Katra even as it makes Katra less useful.
This is the kind of deck that makes me think DWD was right to hold off on giving Xenan its Vow and Painting.
