ok, i'd love to help with the deck, but there are a lot of different ways that this deck can be changed, and i want to help you make the deck you want rather than just throwing cards at you can telling you to use them. so with that being said, i need to know what plan on this deck becoming.

do you have a budget for the deck?

are you going to focus on a more controlling aspect of the deck, or maybe on improvise? something else?

are there any cards that you really like and want to incorporate, or is everything basically on the table to make the best deck possible?

just let me know and i'll get back to you as soon as i can. thanks.

btw switching over for four dual lands is perfectly fine, just make sure you don't overdue it. too many lands that come in tapped can really slow down a deck and cause problems

LithiumHD First of all thank you for responding.I am looking to swap out some cards to make the most of this version of Tezzeret's abilities. I am looking for something to remove / replace with some more Ornithopter.Budget wise I don't really want to put into it anything over $40.Tezzeret's Touch makes me think of the scissors decks so in a way I would love to work that angle as well.I am not that big into control. I was wondering if it would be possible to go an aggro direction with this deck?

Going for a more aggro approach is great. we can flood the board with a whole bunch of cheap artifacts, and either overpower the opponent with sheer numbers, or by wearing them down with Tezz/

First and foremost, i'd like to draw your attention to Herald of Anguish. herald is one of the best cards in standard at the moment and can single really secure a win in most cases.

With that being said, it is possible to drop a herald on turn three in this format, although turn four is much more likely and fairly reliable to reproduce every time.

Running x4 Ornithopter and x4 Bone Saw is a good start. Obviously free artifacts that will easily let you take full advantage of the improvise ability.

Hope of Ghirapur and Merchant's Dockhand are great cards to fill in for the mana slot. Hope makes a great target for Tezzeret's Touch, and the merchant is great for drawing into herald or your planeswalker.

As for the mana slot Servo Schematic is by far the best choice out there. it gives two artifacts right off the bat, and then another one when it dies (most likely to getting sac'd by herald) so running x4 of these bad boys will work wonders

Scrap Trawler is great for a turn 3 play, if you didn't get the herald god hand and can play him. he makes sure that when your artifacts die, then don't just die for nothing, and starts a really nice cycle of cards, keeping your hand filled with cheap artifacts.

also, running two more copies of Tezzeret's Touch will really help with early board presence, especially when its placed on one of your flyers as early as turn 3. yikes.

Reverse Engineer is great here too for drawing cards for really cheap. making sure that you always have artifacts to play in case you need sac fodder for herald, or to better make use of Tezzeret, Master of Metal's ability

let me know what you think of these suggestions so far. and if you have anything you need to ask just let me know.

Awesome suggestions LithiumHD!I looked through my cards but for some reason I could not find more Ornithopters or Bone Saws. I guess it is a by product of my recent move. I did pick up 2 x Bone Saw, 3 x Ornithopter, Foil Scrap Trawler for a $1 from my LGS.I added 1 x Merchant's Dockhand and I am going to order a Hope of Ghirapur. Or should I up the number on those more than two each?I added another Scrap Trawler...should I add more?I am now using 4 x Tezzeret's Touch.I am going to try 2 x Reverse Engineer.I added another Tezzeret, Master of Metal. I do have a third one to add but I don't think it is as need since there is the Tezzeret's BetrayalI am going to order the Herald of Anguish in a couple of days...Anyone have thoughts on whether it should be a 2 x or more?The cards in the sideboard are some of the things I took out of the original deck.One card I thought about adding to the sideboard is Underhanded Designs

running x2 of Merchant's Dockhand is fine, he will smooth out draws in the later game, and is a cheap artifact that can pump out your Herald of Anguish as soon as possible. speaking of which, going full aggro with cheap artifacts means that you need to have herald in your hand as early as turn 4 reliably, otherwise filling the board with just cheap artifacts is ok, but most of the time wont have that extra power to close out a game like the herald does. so for herald going with x3 or x4 copies even is good.

going a full x4 on the Hope of Ghirapur is an option. being a flyer it means that it is a great target for Tezzeret's Touch just like Ornithopter, just be careful because it is a legendary creature meaning only one can be on the battlefield at any given time.

x2 or x3 Scrap Trawler is good. you can draw him reliably with x3 and it doesnt raise the average CMC of the deck by too much.

x2 Reverse Engineer sounds good. opens up cards draw but limits how often it will get stuck in your hand early game

x2 of Tezzeret, Master of Metal is plenty enough. with 6 cmc, adding more would be counter productive. he costs too much to have just sitting in your hand. shame he doesnt have improvise.

Underhanded Designs is good for a sideboard card. you will have PLENTY of free artifacts to play, especially with Scrap Trawler and Servo Schematic

Tezzeret's Betrayal also has really high cmc, making it hard to cast reliably, so just make sure that you dont have too many in the deck, otherwise you can get stuck with multiple copies in hand and no mana to cast them
