Love it! +1!

I think you might be overlooking Gearseeker Serpent. I play two of them in my version of improvise and, if unanswered, they are always game enders. Also being able to cast that and a Herald of Anguish on the same turn is DEVASTATING.

Nevermind homie I like your deck a lot better than mine, keep doing what you're doing!!

nickfrostslide thanks for the feedback!

I did not even know that Gearseeker Serpent was a thing, somehow it flew under the radar I guess. I could try swapping two of those in for Bastion Inventor, and just run the two inventors in the side if you think that would help.

No prob! If you wanna check out my version of this deck feel free. It's pretty similar to your take now because it seemed like your deck worked WAY better than mine.

Looks pretty good. I was running something very similar, but I added red for Maverick Thopterist, Unlicensed Disintegration, and Pia Nalaar. The 0 cost artifacts were great for ramping to Herald of Anguish, but left my hand empty most of the time. I would suggest dropping some of the puzzleknots and adding Key to the City and Pacification Array to help get through their defenses. Also Key to the City works great with improvise since you don't have to pay to tap it.

GabeBurch thanks for the feedback!

When I was building the first version of the deck, I thought about putting Key to the City in here, but ultimately decided against it. While more evasion would certainly be useful, it seemed too slow and I'm unsure how much value I would actually get off of it. I like the synergy that Metalspinner's Puzzleknot has with Tezzeret's Touch and that it immediately replaces itself. I need to do more testing against actual decks to see how much of a problem I have with breaking through defenses, but I will certainly consider it in the meantime.

Also consider Hope of Ghirapur with Tezzeret's Touch. Swing with 5 in the air, then sacrifice it back to your hand
