archiving Pokemons

If by "archive" you mean using a nomenclature system, what I use is fairly common but it needs some special characters to be able to fit in the name space available. I start with a 2-digit number representing IV percentage to the likeliest average, followed by the specific IVs for each stat using Unicode encircled numbers 0-15, and finally adding a short abbreviation for the Pokémon's moveset.
So a 46% IVs, 10atk-1def-6hp, Pound/Hyper Beam Chansey would look like this:
46 ❿❶❻ PnHb.
As for sorting out Pokémon for evolution sprees using lucky eggs, just type "evolve" in the search bar when looking at your collection and it'll filter out any Pokémon that can't evolve either to being Max-stage, not having enough candies or lacking special items, and leave you with only the ones that can.

IV% /moves /attack IV
e.g. a 98% Tyranitar with Bite/crunch and a 14 attack: 98 B/C 14A. If the same ttar had fireblast instead I would do that in lower case because it's not an optimal move like 98 B/fb 14A.

I don't do anything besides my top 5%. Don't see a need to waste time and give names to Pokemon I'll never care about.
