My most creative deck yet

as the title suggests, this is what i feel is my most creative deck I've ever made https://moxfield.com/decks/Xu8b4BK9OEuO_CzQ5DB8tQ

It's a dual "secret" commander deck using Mister Negative and Rowan, Scion of War with a legendries matter subtheme enabled by my commander. Let me know what you think, and if you have any suggestions!
