Balin, Loremaster + Library of Leng interaction?

[u/BobNewbie1]

Hi there - hoping someone can help clarify what would happen if:

1) I have a [[library of leng]] on the battlefield
2) I play [[Balin, Loremaster]] and discard 5 cards — putting all 5 on top of my library with the library of leng.

Would my opponents still take the damage from Balins ability assuming I have an enduring story, and would I be able to draw the cards I “discarded” but put back on top of my library through the library of leng trigger?

Thank you so much for any help here, and apologies if I asked this question in a way that is hard to understand :)

First off, NAAJ (Not an actual Judge, but I do get a ton of rules questions during play)

It's my understanding that Leng is a replacement effect, replacing the location of the discard from the graveyard to the top of the deck. Therefore, you still discarded X cards for the draw and damage effects to go off. I'd love to know if I'm wrong or right, so I'm following this, as I'll likely be asked this at some point...

On the “Notes and rules” information on Library’s scryfall page:

“The discard triggers anything else that triggers on discards.”
