Hi Peeps,
ages ago I decided to organize my collection by set for reasons 
- Sorting your collection in other ways has it’s advantages I am sure … Anyhow… for people out there that also sorted their collection by set I have some ressources that might help building a legal card pool:
System Core 2019:
If you want to build the SC19 as a physical set here are two decklists for Corp and Runner with original card numbers, showing you where to find the cards needed (click Actions → sort by set on Netrunnerdb):
Terminal Directive:
If you just want to know which cards to pull out of the “now” rotated Terminal Directive Expansion, look at this picture showing cards that are still legal today:
Lunar and Creation and Control:
These sets have also rotated out of the legal card pool due to the 3rd Rotation. Cards still legal to play were reprinted in Nisei’s Ashes Expansion and from what I have gathered, more of them might be reprinted in future releases. Here’s a pic of the old cards reprinted so far: (actually False Lead is from Genesis and Colossus from TD derp - should have called this Saved from 3rd Rotation I guess)
Legal FFG Deluxe Expanions:
Honor and Profit
Order and Chaos
Data and Destiny
Reign and Reverie
Legal FFG Cycles:
SanSan
Mumbad
Flashpoint
Red Sands
Kitara
(Magnum Opus - POD only)
Legal Nisei Expansions:
Ashes
Magnum Opus Reprint
Most Wanted List: Banlist
Since 20.06.2020 we have a banlist instead of a most wanted list.
All currents can go into your rotated binder for now e.g. but I assume they are going to stay there.
Here’s some useful links with visual representations:

That’s it for now, hope it helps someone. Did I miss something or make a mistake? Please let me know.
So long and always be running,
Late
