Transgress the mind is great and tezzeret ambition or pore over the pages instead of succumb to temptation and heart of kiran how u going to crew it??? But yeah looks nice

Isn't Tezzeret after Metallurgic "win more" i.e. doesn't actually help you win since you've already won. If you already have an army of tokens I guess you could use Tez's -2 for a little removal but you've probably already won and it's not better removal than Ajani's -2 (obviously it's 2 mana cheaper). I'm not seeing the synergy here.

I love this! Such a good take on, Baral, Chief of Compliance and Yahenni, Undying Partisan could be good too but idk what you would take out

Luffy1369 Thank you very much for the comment and suggestion. Since the banning of Smuggler's Copter and Emrakul, the Promised End, the deck can now play a little slower. That makes room for Transgress the Mind.Heart of Kiran gets crewed by Liliana, the Last Hope or Tezzeret the Schemer.

InfuriatedBrute Thanks for the comment. Yeah I was testing to see if Tezzeret would fit into the generic Metallurgic Summonings I have been running. Now I use Trail of Evidence instead.

jacoby0813 Thanks man! Baral, Chief of Compliance dosn't really work in the deck after i've been testing it :( Yahenni, Undying Partisan looks better in a aggro midrange strategy

Idk where youd fit it in but metallic rebuke is a card i have been super impressed with upon inspection. It is a worse spell shrivel but but i believe that the improvise makes it awesome especially in a controlley artifact deck like this. Ideally i see swings with heart of kiran(which has vigilance) and then can be tapped during the opponents turn to fuel improvise. But very cool! I tried brewing a control deck with tezzeret like this but in grixis colors. Unliscenced disintegration is a hard card to pass up. Upvote from me

Jakoruz Thanks for the comment and the upvote my man!

Regarding Metallic Rebuke: I like it a lot, but in a different shell. This deck generates artifacts a little too slow for the card to excel, but in a more aggresive strategy with Ornithopter perhaps. If this deck takes a more artifact based form, I will for sure add it to the mainboard :)

Splashing red could work if you needed more removal like Harnessed Lightning or the really good Unlicensed Disintegration. I decided not to go Grixis since Fatal Push and Grasp of Darkness are really efficient removal now.

Thanks for the feedback and your suggestions! The deck will be adjusted a lot in the coming month. So check back regularly if you want to be updated :)
