I really like this deck! 5/5 Scissors are always awesome. Maybe add Mishra's Bauble for some card advantage?

This deck could be standard.

Thanks for the feedback cowboy_hippie and Meat. I do like Mishra's Bauble, but I just made this deck standard.

You could splash red for Shrapnel Blast and Generator Servant.

Stoic Rebuttal and Thoughtcast if your not doing standard

Maybe a Lens of Clarity sideboard?

Thanks for the feedback Ninjadude51, emvill7e, and Hampsa. I am considering spalshing red. I want to keep this standard. I would add Lens of Clarity, but i'm not making a sideboard right now.

Hi, I have a same deck... The perfect combo is Daring Thief + Springleaf Drum / Chief Engineer... This link can help you with build.

Thanks ona.skora

Any thoughts on Ghostfire Blade?

I have thought about Ghostfire Blade, sailboats. I was going to use it, but I found Aqueous Form. I could take out an Aqueous Form and a Juggernaut to put Ghostfire Blade in though. What do you think about that?

Check out my deck for ideas, its quite similar to yours! I found that ghostfire blade is definitely a must if you're playing artifacts in standard.

Why colossus? You're really not going to get the ability off which is what he's all about

firemanefruitcake, Colossus of Akros is just an pretty good card all around. You can get him out pretty easily with Chief Engineer and then just block all threats with him until you can get 10 mana. I would like to put in cards like Blightsteel Colossus, but he's not standard. Any ideas to replace Colossus of Akros would be helpful.

Maybe consider taking out Colossus of Akros for more Scuttling Doom Engine. You could also consider playing Renowned Weaponsmith to get your artifacts into play faster.

Take DominantEgg's advice

have you looked into phyrexian revoker?

Some Disdainful Strokes wouldn't be bad :3

Thanks for the feedback DominantEgg, firemanefruitcake, Antihero6396, and Dreamer1997. I added a few more Scuttling Doom Engine and took out Colossus of Akros. I like Phyrexian Revoker, but I don't think it fits too well in this deck. I also would like to add Disdainful Stroke, but I can't find a place for it right now. Thanks Everyone.

I think that you could take out the Aqueous Form for counter because all of your atacky creatures have evasion.

Check Renowned Weaponsmith

Forget soul and juggernaut this deck wants to win fast and make 5/5s fast. You want Dakra Mystic in there so you can control your draws and your opponents and Springleaf Drum to tap dakra for mana and trigger inspired. Springleaf is also another target for ensoul. This is a demonstration of good synergy that allows you to quickly get going and is even better if your opponent is playing courser of kruphix. Also you want to play Stubborn Denial in this deck more than dissolve because denial is a full counter for 1 blue vs any spell that would stop your 5/5 because as long as you have your main threat online ferocious is turned on.

Sorry i meant to suggest the U/B inspired gold card and Pain Seer in addition to dakra and drop chief and tinkerer. These creatures will just win games faster getting you what you want. Problem with engineer is that this deck has few creatures and you end up maybe able to tap 2 creatures ever at the most not netting a ton of mana. So drum gets you mana and a target for ensoul while getting you extra value from inspired driving you forward. U/B is the way to go if your not splashing red.

Disciple of Deceit was the gold U/B I was thinking of. So if you hit another of these or a seer exc 2 cmc card you now tutor out your ensoul everytime everygame.

Wow thanks for the feedback ColdHeartedSith. I added Stubborn Denial, Dakra Mystic, and Renowned Weaponsmith. I'm considering the idea of taking out Soul of New Phyrexia and maybe Juggernaut, but I don't know what to put in it's place. I want to keep mono blue too. What do you think about adding Springleaf Drum instead of Soul of New Phyrexia or Juggernaut?
