Looks like your typical affinity deck. Spell Pierce is really odd in this list though cut them for sets of Galvanic Blast and Thoughtcast

@bman5604: I looked at a number of net lists, and while the wide majority went with the Galvanic Blast and Thoughtcast sets, an article I read on Star City Games made a good argument for some kind of countermagic against all the noncreature cards that can slow down or just flat out kill affinity's momentum. Primarily, it'll answer Stony Silence , Ancient Grudge , and wipes fairly well, among whatever other artifact hate is in people's sideboards. Here's the link, and thanks for commenting!

Be sure to give credit where credit is due. Since you copied and pasted this list. it makes since but still odd. If u feel like everyone is hating on u it's because they are. Robots are sick fast and there is a ton of artifact hate available. He'll I run Shatterstorm in most my decks because I'd rather have it then not

Thanks for pointing that out, actually. I hadn't even noticed that the lists were that similar. Believe it or not, I made all the decisions for the cards in the deck by comparing a number of other affinity lists against each other, and it just turned out this way. I'll be sure to include that in the description though. And I don't mind the hate really. Artifacts would be a bit too good if there wasn't that much hate for it out there, but anything to answer that hate will make the whole deal more guaranteed. Shatterstorm won't do much if I Spell Pierce it. Also, do you have an opinion on Etched Champion vs Master of Etherium ? Not sure which one I like more at this point.

Tezzeret, Agent of Bolas

Both are sweet it comes down to preference

@Sam_I_am: Might include him as a one of, but his cost is a little too high for the deck. Also, I'm usually not fielding enough artifacts to make his -4 win me the game, and the one turn delay till you can activate it makes me a bit unsure how often he'll stay around that extra turn.

It confuses me that this site says that black is a quarter of the deck's color pie when Vault Skirge is the only black card I see in the deck.

Same. I think it may be counting the BB from Cranial Plating insta equip cost, but I don't know why it'd do that. And thanks for the +1!

I'm getting the feeling it's because most of the people on this site see EDH as the only legitimate format because it's "casual" and that color identity is a legitimate property.

No it's accurate you have more spells that are colorless then you do that have actual color in its cmc

I like Tezzeret, Agent of Bolas in there maybe as like a 1 or 2 of because you could turn your Darksteel Citadel into 5/5 indestructible. seems powerful but i know relatively low mana cost is important in affinity

The thing is, Tezzeret, Agent of Bolas has a tendency to show up in legacy affinity decks, so I assumed that there must be a reason why.

He works better in legacy because you've got access to the artifact lands, like Seat of the Synod , Tree of Tales , Great Furnace , etc... Those all make his -4 a lot better when it gets off, which is easier to do with free control like Force of Will and what not. His -1 would be pretty good in modern affinity, which is mostly why I'd consider him as a 1 or 2 of, but his +1 doesn't do much since there aren't any good artifact bomb spells in modern for him to tutor up. At least none that would work with the deck, in my opinion.

I'd cut 3x Steel Overseer for Etched Champion . Etched Champion + Cranial Plating = win.

I think I'm going to keep the Steel Overseer s, but you're definitely right that Etched Champion would be great in the deck. I'm still not sure if I want to run 3 of him, or 3 of Master of Etherium . The two don't work too well together, unfortunately, so I think I'd have to have one or the other. Right now, I'm leaning towards Master because he provides an instant benefit the turn he comes into play, not to mention the fact that he's usually a fairly large body to have around as a blocker or attacker. Champion is a smaller body, and doesn't do anything for me the turn I play him, though admittedly he pretty much just wins the game once I get Cranial Plating or enough tokens on him. I might change it later on, but for now I think I'm going to stick with the Masters. Thanks for the suggestion though.

averaged turn 3 to 4 win. very nice.

I think Master of Etherium and Etched Champion work beautifully together. They buff each other. Steel Overseer is decent, but Etched Champion is a better card, granted it's 1 more CMC. But with Mox Opal and Springleaf Drum , Etched Champion is a turn two play.

@ aeonstoremyliver: Master of Etherium and Etched Champion don't work that well together because the Champion's metalcraft ability gives it protection from Master of Etherium 's buff, being a blue creature. And Steel Overseer and Etched Champion serve completely different purposes in the deck. Overseer will buff my other artifacts, while the Champion is basically just an attacker (admittedly, a very good one). Right now I'm thinking I'd rather have the Overseer, largely because Etched Champion and Master of Etherium just don't work that well together, so I'd rather not have both in the same deck. I'll do some more playtesting though to see whether I like Master of Etherium or Etched Champion better though. Either one could fit the slot in the deck, and both definitely have their merits. Thanks for the recommendations and the +1!

@ tarnash: Glad you liked it, and thanks for the +1!

Incorrect sir! Protection from X means that it cannot be targeted by, blocked by, or enchanted by X. So, they do work beautifully together! In any case, just my opinion with the suggestions sir :-)

@ aeonstoremyliver: Learn something new every day. Thanks for the tip! Had no idea that that was all protection referred to. In that case, I'll definitely do some playtesting and see how that works. I'm thinking I'll probably make the switch to a degree, maybe taking out one or two Overseer's for one or two Champions. This is terrific news. Thanks again!

Certainly!!!

I forgot to mention 'damaged by X' as well... Remember DEBT: Damage, Enchant, Block, and Target, when dealing with Protection. So Pyroclasm , Bonfire of the Damned , etc. would deal no damage to Etched Champion if Metalcraft is enabled.

Global effects that don't specifically target a creature with protection do work. In the case of Master of Etherium it's to your benefit, however Wrath of God is not. Does that make sense?

I think I've got it. So board wipes, whether they be destroy, exile, -X/-X, or Terminus like effects and so on would just about be the only things that would work as removal. And of course sacrifice effects. That's all I can think up right now, but I'm sure there's probably more I'm not aware of. Thanks again for the rules tip.

Yessir. Creeping Corrosion hoses Affinity decks. I run 3x in most of my sideboards. Really just to tick my friend that plays Affinity off (and it's a fast deck...), but I digress.

That being said I would recommend more counter magic in your sideboard.

Since your running blue, have you considered adding Stoic Rebuttal ? Can counter any spell and will be cheaper with all the artifacts you have out.
