@ducttapedeckbox, Hour of Need provides a much better finish. At five mana, we get two fat fliers out of dead draws and all our weenies. Yes, Izzet Keyrune makes for openings where we immediately have our opponents on the clock. Which would be enough of a case for me to keep it as a three of. If the deck could win before turn five. I'd rather be able to make 4/4 fliers at instant speed.

Perhaps the best answer is Hour of Need should find its way in one way or another. Chief Engineer and Ornithopter are good targets in the late game and it can't hurt to have a second card to win with.

I have to agree with Electric that having a second win con is always preferred. Stick Hour of Need in and playtest with it, you won't question it after you do. I would still like your feedback on my deck, thanks.

I know that with convoke you can cast more expensive burn spells like STF but with Shrapnel Blast already killing pretty much any threat in the meta, why not just go for the tried and true Lightning Strike or Magma Jet for x2 scry?

Electric, Ensoul Artifact + Ornithopter is cheaper and stronger than Hour of Need though

@Doomed_Traveler77 yes, but, Ensoul Artifact misses Chief Engineer and is less evasive on Phyrexian Revoker .

Doomed_Traveler77 relying on those two cards in conjunction with each other Ornithopter +Ensoul Artifact in a deck being that there is only 4 of either of those in the deck of 60 is just a bad thought process, yeah Ensoul can be on other artifacts, but the combo itself targeting Ornithopter is too limited in its uses especially with the Theros block and all the removal focused to towards enchantments and artifacts now. This archetype is just not there yet when it comes to standard competitive, and probably won't be until some Khans is spoiled, even then it is a farcry in the dark. I agree with Electric when it comes to Hour of Need if the deck still wants to have fliers present.

Due to all of the input and discussion, I've switched out Izzet Keyrune for Hour of Need . I agree that it has much better utility and can, at its worst, make some nice creatures out of my creatures that drop off late-game. I will playtest it (especially when I hopefully assemble this deck in paper this weekend) thoroughly as soon I can.

Now onto the next discussion point: Stoke the Flames . I still think it's too slow, and would prefer something a bit faster. I also want to avoid 2-drops, which encompasses Lightning Strike and Magma Jet . Am I crazy for thinking that I have too many 2-drops?

I really do love this deck, it's quick and dirty. But I don't know about that hour of need. Every time I Playtested the deck and got him into the hand, the field already will have a 5/5 with either flying or indestructible, or is a 6/6. And, why not Lightning strike instead of Shock (just curious since since from my experience that 3 dmg always seems to win me games).

Also, if you want you can try this against my Land Destruction Deck that I am using for tournaments. For the love of Lands

Actually, I take back the Hour of Need Comment, it's a good back up card. But I wonder if there is something better then that?

@ 8BitVillain -- UR Artifacts is missing 1-2 pieces right now to make it a really strong deck. Hour of Need isn't one of those cards, but in the current Standard it's pretty good. We just have to hope that Khans gives us those cards we need.

@ducttapedeckbox I've spent a lot of time looking over all the shells for this build. I think you've done a fantastic job. I'd love to get your take on any notable differences between yours and mine. Shrapnel Engine. Also would love to get some background on how you built your sideboard. Thanks again for the time.

is sharpen blast legal

I think that Generator Servant is a really good fit in here especially with a turn 4 Scuttling Doom Engine .

@ Electric -- I'll take a look this weekend. Remind me if I forget!

@ seth11 -- Yup, Shrapnel Blast was reprinted in M15.

@ SwaggyMcSwagglepants -- I've been thinking about that, but I'm not sure where he'd go.

Phyrexian Revoker is more of a sideboard card.

GamerSonX I agree, switch it with Generator Servant same CMC & P/T...

i think it all depends on how reliable Ensoul Artifact is. if ducttapedeckbox can get it consistently, then Phyrexian Revoker . if not, then Generator Servant

don't worry. i still keep up with everything going on here XD

I think his curve is too forgiving to put Generator Servant . The card is awesome and a hasty Scuttles is the dream, but the Servant feels kinda wasted here. Even though Phyrexian Revoker is an usual sideboard drop, just the fact that it is an artifact seems to fit better [ Ensoul Artifact / Shrapnel Blast ].

@ GamerSonX, Doomed_Traveler77, tempest, and maioflw -- Refer to post #8 as that conveys my general concern of adding the Servant. I'm not running enough bombs. Sure, he might help get a SDE out but many times he won't. He definitely has a home in a deck with a heavier creature devotion like OhTheNoise's Soul of Neil Patrick Harris, but I'm not so sure about my deck. I'm more than willing to discuss this further.

Also, tempest, it must be hard with that awesome Dimir deck you got goin'. I'd give it a second upvote if I could.

lol. its not that bad :P i don't get nearly as many comments as you haha. i'm also running out of tokens after i got the t-shirt so... i'll definitely be pretty active when khans of tarkir spoilers come out XD

anyways, back to your deck. have your considered Thassa, God of the Sea ? i think it could replace Hellkite Tyrant and be put in for Hammer of Purphoros if you need it. what do you think?

Thassa, God of the Sea would filter your deck with the recurring scry, helping in setting key pieces, and also make the ensouled artifacts unblockable, or Scuttles if they for some reason can block it. A fine possible addition even if she rarely comes online ;) I'm gonna maintain my opinion that Generator Servant is really wasted here :p

@ tempest -- Aha I still have a decent amount left if I come up with another idea/to use on this deck when Khans comes out :P

I really like Thassa, God of the Sea . Like a lot. She even has a legitimate chance of coming online. I'm going to go out and suggest two mainboard. Thoughts? Tagging you too maioflw. I also agree about the Servant.

are you taking out Bident of Thassa for Thassa, God of the Sea ?

Definitely not, I really need the card draw. I was considering a Revoker or two, but I'm not sure.

Yeah, the Revoker is the one that would impact less the rest of the deck in my opinion [of course removing artifacts isn't perfect in this deck], so if you gotta remove something that is the way to go. Is the Trading Post working out for you? If it doesn't have a lot of an impact you can also test taking it out for her. I can't test this right now, but I think both alternatives are viable.
