I’ve seen that, and despite what Ondrej Strasky says I’m unconvinced. When I’ve tried the lists they feel oddly disjointed, a hybrid that doesn’t really work. There’s a lot of very powerful things they can do when it all goes right but in my testing things had to go exactly right for it to be measurably better than Bant or UW. Because it (normally) cuts on Rattlechains and utility cards it lacks the flexibility of UW, and because it cuts creatures the Company’s are less impressive than just Bant.

My opinion is that it’s a run-well deck. When does its thing it’s far better than the alternatives. When it’s off or something goes wrong, the seams burst.
