I actually am thinking Illness in the Ranks is better than Thorn. Stops Blitterblossom and Splintertwin.
1 black mana and all tokens get -1/-1. Enchantment, so they have to deal with it once it's there.
Basically, if I were to go to a modern ptq with this deck my sideboard would look like this;
2x Illness in the Ranks
1x Thorn of Amethyst
2x Spellskite
2x Spell Pierce
2x Dismember
3x Thoughtseize
3x Whipflare

I'm not going to pretend to know what the modern meta is, I only know of splintertwin and blitterblossom. Illness in the ranks is just a giant middle finger to both of those. I run Spell Pierce and Thoughtseize in legacy, so it can't be terrible in modern right?

I also would try to find room for 2 springleaf drums mainboard, because color fixing is important. And turning ornithopters and memnites into turn 1 mana is good.

Maybe he's mad because someone played an infect EDH deck?

All of the following is my opinion but what I would take to a ptq
Sideboard;
3x Thoughtseize
2x Thorn of Amethyst
2x Spellskite
2-3 Spell Pierce
4x Dispatch
Mainboard
2-3 Thoughtcast over Serum Visions
2 more Vault Skirge over 1 Overseer and 1 Batterskull.

Let me know how chief engineer runs in modern, I know I crushed people with mine in legacy.

I can't say I've ever built an artifact deck for casual purposes.

Would Glimpse into Affinity count as toy story? Maybe?

Tamanoa. Most troll card to build a deck around for multiplayer. Some ankh of mishra, searing meditation and some burn spells like pyroclasm and you've got yourself a hate deck.
For standard you simply must build around Nissa, Worldwaker, Ral Zarek and The Chain Veil. Infinite walker combo is infinite.

The only thing that makes affinity viable in legacy or modern is it's stupidly fast aggro capablility. Chief Engineer definitely makes playing bigger things possible, like a turn 1 master of etherium as a 5/5. But you gotta be careful, you don't want to swamp your hand and draws with too many things you can't play simply because you lack engineer, whether he was removed or you didn't draw him.
Thoughtcast is also an option, over what I don't know. But it's usually one blue mana for two cards.

Shrapnel Blast and Scuttling Doom Engine. Swing, sac to blast, 17 damage. Get wrecked.
I would run Springleaf Drums over Batterskull. A little unoriginal, but it does good things. In addition to speeding up hand pooping it counts towards cranial plating and is another turn 1 drop that fixes mana.
I tried running steel overseer in my legacy affinity, but he just seems too slow for what the deck wants to do. Does he work well in modern? I would finish the playset of etched champions and mainboard 2 ethersworn canonist. Canonist or Dispatch.
Other than that looks good. I don't play a whole lot of modern, but if I did I'd likely run affinity.

Just remember kids, vines of vastwood over simic charm and blight mamba over necropede and this suddenly becomes pauper legal.

Painter's Servant, name red, blow up everything with hyrdoblast. Also, it is very easy to win with just 2 or 3 hedron crabs on the field. After all, 2 hedron crabs +1 fetch is 12 cards, and since fetchs are in just about every deck archive trap does get there. Grindstone and Painter's Servant are just good compliments that can't be turn 1 Iona naming blue.

Then the only way to push through damage would be to give it trample, which would still kill your creature, or to give it protection of which there is really only one viable way to do that. In the end you do more damage but it's slower.

But that's next turn. Infect is all or nothing. Yes, infect can still win mid game with a well placed distortion strike or blighted agent or inkmoth nexus, but as a rule of thumb infect is looking for the turn 2 or turn 3 win. That is simply because in the modern or legacy scene, if you haven't won by turn 4 with an aggro deck, you are going to have a very hard time winning.

Painter mill.
I've had good luck wiht it so far. I've crushed elves and reanimater, along with show and tell. So it works, just gotta know when to mulligan.

Surgical Extraction and Tormod's Crypt stop emrakul. I played legacy mill recently with painter's servant and grindstone. Archive traps were there, ghost quarter was there. I never had a problem casting the traps since fetches are so relevant in the format.

I meant for the turn 1 blightsteel colossus in legacy.

M15 has raised my hopes and given me one card that I will buy every copy of, ever that card being Chief Engineer. My hopes for Khans are too high.

Bundling them up in midrange/aggro/control basically describes all decks except for mill and burn. I mean there were more variations with different interactions. There was more that I could do as an opponent to blue control varients. Blue control was far more interesting before rtr, by more interesting I mean it was more than, drop a land and pass the turn for 8 turns.
Before, blue control could easily be blue control aggro or blue control burn or blue control mill. With rtr all you saw were blue and white control decks that stalled until turn 8-10. Only with the theros block did some start splashing green.
Just saying, it's getting old. It's like seeing someone play sneak and show or elves in legacy.

I disagree. There used to be a greater variety and more interaction for the players. There were many more ways to abuse the stack in standard. From everything I've seen since rtr, creatures have gotten stronger, spells have gotten weaker, and nothing beats mono black or blue white control. Blue white control has been dominated standard since m14. For instance there is no competitvely viable way to run burn in standard. It used to always be an option. Not anymore.
Blue White Control, Mono Black that sometimes splashes green, a variation of Red Green monsters. That's it, those are the only real competitive decks. Sure, you could run a mono red aggro list or white weenie, but those only sneak in wins. I played variations of many of those decks in standard, trying to make it work. Sure, sometimes I top 8, but that's moreso the lack of skill of my opponents. Top 8 players crush anything not meta.
Legacy and draft are the only events I go to, just because with legacy the meta is there, but there is a huge variety, and you can still make good decks that will win tournements that are new and fun.

I've seen the dredge deck. And it will lose to a good control player. They just have to hold on to azorius charms or d-spheres.
It will also lose to good midrange players. And it's all because the dredge deck requires too much setup time.
Blue will also have that one mana blue instant bounce spell in m15, making it better. Knowing that rtr and m15 will be standard at the same time just sounds terrible to me, strictly because we get a lot of interesting cards, but the meta will not change.
