Even on like, a fundamental level, I really don't think I can make an exchange like that because it reduces the aji in the corner. I can make that hane whenever I need to, but doing it right now is like a gote sequence that lets white take the initiative when the important part is the split.
To me, that hane is a move you want to play because white started the Magic Sword and you want to simplify the number of variations you have to read, and there is no Q10 stone. It's a cop out move imo. And I really don't think I have the luxury of playing it.

Two authorities, Takao in the Dictionary and Yang in Whole Board, says that starting the Magic Sword joseki with the black outside attachment B29 was a bad choice for Black. B33 is better than the hane underneath for the reasons Violence cited but the followup by White at the circle point makes W28 too close to a strong black group and White's formation on the right side is undermined.

I forget where I read it, but some pros apparently consider the magic sword a refutation of the 1-space high approach when white has a stone at Q10.
In other words, Violence may have chosen a clearly inferior joseki.

Korean and Chinese players are experimenting with the outside attachment. I believe the jury is still out on the effectiveness. I haven't seen the Magic Sword response in my study and if this sticks, it will be another 20 years before we get any publication about it.
I bet modern pros have refuted the Magic Sword line in study rooms. (i.e. white gets only a 95% result instead of 100%) It is worth comparing to the more common pattern:
White can get this result with little/no variation possible by black and it looks good. Here is a useless stat: White won all 7 games since 2003 that this partial pattern (with Q10) has appeared.
This begs the question of why I've been seeing so much one-space high approach on Tygem recently? My guess is that the usual two space low approach is boring and over-developed.

Database says you can , and my weak mind likes the result: territory in the corner for White, Q10 stone already in a spot White wants to harass the right side group, with a secure Black group in the lower middle-right, a spot where the territorial chances weren't huge to begin with.

Actually I think this is ok for black, taking the corner and breaking white's right side. Black doesn't need to invade the lower side, g5 would be good enough to grow the left side and make white feel overconcentrated if he defends the lower side territory. Maybe white could get a/b in sente then g7. Or just tenuki? Or attach on top with b?
If white ever gets to play 1, this sequence is forced, and white has like 1 hundred million liberties(It's like 7 here, but you get the idea. It's a liberty making tesuji.

Isn't this result just insane?!? I got the corner in sente, and I ruined his Kobayashi framework, and he barely got anything out of it, and the side is low and inefficient... Does he have some other plan?

Comparing these two results, I haven't lost anything with regard to the group that's currently cut off, it's still at two liberties, it has the same running moves as before.
The exchanges I've made make sure that white doesn't have a nice endgame sequence/ability to affect my life and death

Violence is right his push has an advantage for yose/eyes in the corner, but it does have a disadvantage in that white can play like this to unconditionally capture the 2 stones whereas before they could possibly run (but this does give black some sente moves around k3 or more yose at n2). But I do quite like his line.
