I started working on JP's last list when the article came out, my new list is quite different now. It still seems like a toy to me in playtesting (lots of cool synergies but no real "I win" combos) but it's getting better. Myr Retriever really increases your resilience to Force of Will, however the smart opponent will counter Disciple of the Vault, without which winning is very clumsy (to the point where I now run 2 maindeck x-burn spells).
However, once the draw engine starts in proper, it's very hard to lose. As a matter of fact, last game I played I got 2x clamp and an ironworks online turn 3, at which point I proceeded to draw my ENTIRE DECK, abuse yawgwill, and torch for the kill with 3 non-acadamy lands in play (I had over 70 mana, though I didn't use it all in case I needed to fire off the second torch after the first being countered). That's impressive considering I started drawing with 2 available mana.
The arcbound ravagers don't fit the deck. While they provide a second win condition outside of disciples, they're most often used to fuel the clamp, which is inefficient. I feel thoughtcasts are a better inclusion, as they aren't dependant on clamp to dig through your deck. The x-burn is a faster alternate win condition with less incidental inconveniences (blockers ,summoning sickness etc). Because I don't have ravagers, the ornithopters are out in favor of shield sphere (even though thoptor can get clamped and swing for one

)
Mind's Desire screams out for a slot here. When you're generating mana, drawing cards, and dropping mana artifacts on the table, this thing is a beast. Sometimes its dead, but when you're starting to fizzle, flipping over 8 cards almost always gaurantees you win right then (especially when you flip yawgwill, play the 6 nonland cards, drop artifacts out of your graveyard, and desire again for like 20).
Seat of the Synod > Ancient Tomb. You need the coloured mana, and they can be fed to the ironworks.
I couldn't resist running mind twist. When you're throwing around large amounts of off-colour/colourless mana, why would you NOT want it?
I really want to run shattering pulse. Null rod, damping matrix, trinisphere, chalice for 1, random counter-imbued iscochron scepters all ruin my day. I also want critter kill, as a quick fatty, goblin welder, or enemy disciple is fear. I feel the correct way to handle this is cunning wish, but I don't know what to cut

. Despite all these vulnerablities, the real unfortunate thing is the deck requires both clamp AND ironworks in play to function.
