If you sac a myr retriever to krark clan ironworks in order to pay for something you're casting then myr retriever is already in the graveyard when myr retriever's trigger goes on the stack allowing it to retrieve itself. This is because the sac effect of ironworks is a mana ability and thus moves the creature you sac outside of the stack itself.

Yep. There is a combination of cards that will stimulate a Turing machine.

There's barely any cards that get something back after it's been regularly exiled by shit like Path to Exile

It's all about intent. Unless your opponent has Squee, the Immortal, Riftsweeper or Pull from Eternity in their deck (and no one does), when you exile their cards, if it's not to play them with an Etali-like effect, they are gone for good.

That's kind of been the standard for the history of the game though. One of the first things I teach a new player is that every rule is followed by a footnote that reads "unless a card says otherwise."

Exile has always been the "don't touch me til you do the thing" area.

its all counters, and fast plays. i seen some recent cards on and off, alot of them seems to play on "exile x amount of cards you can play this without paying its cost"

As far as I understand, a bimbo is commonly a person that is superficial and put a lot of effort in an exaggeratedly hyperfeminine appearance, and people into bimbofication will sometimes want to be (or to look) dumbed-down to fit that persona, and I think this is what this post is referring to.
The difference between graveyard and exile in this context is that graveyard for non-creature spells is like a pile of old memories that you keep and can still access, while the exile is like becoming non-existent or out of reach.
Now that I look into it, though, I feel like the mill cards flavor is pretty fitting for the theme. Besides the mill and grind cards, it's a lot of stuff that plays with your head, like "Mesmeric Orb", "Mindcrank", "Mindskinner", "Fractured Sanity", "Memory Erosion", etc. While the cards that exile stuff from opponents libraries are less focused besides a few Faeries.
