Not a lot to add. It looks like completing Math will take me into the summer of next year.
I achieved this maybe a year ago but never got around to uploading the proof. I’m hoping to come back to this game at some point.

Apart from foils, I now have 2 copies of every 1-3 diamond card. I just need to get 1 more each of Mega Gallade, Typhlosion, Wailord, and Weezing. I’m literally day away from completing the last low value themed collection that I hadn’t caught up with yet also.
I am eight foils away from completing 1 of each diamond card for Deluxe Pack: ex, but barely started for Deluxe Pack: mega so far. My next plan will to try to get 3 of every 4 diamond card, get any easy gold frames that I’m close to, and then do trades for foils, shinies and 1 star cards as I await the next series. Maybe they’ll increase to level 70 in this coming year.
Last weekend I finally caught Raikou to complete the living gender-form dex for all native FRLG species!
I caught up on my second save file, obtaining Deoxys-Attack (increasing total to 422), and doing all the Sevii stuff and breeding required to get the other 17 Pokémon as well as the Squirtle line before attempting Suicune, which I captured on the second successful trapping right at the end.
Now, on the third save file, I’ve already beaten the elite four and all I need to do now is unlock the National Pokédex, complete the Ruby and Sapphire sidequests before I can capture the final Pokémon in a Poké Ball: Raikou!

Yesterday I got 10 closer by hatching Shellder, Scyther and Elekid and evolving into Cloyster and Electabuzz. Female Bellossom, two Slowking and two Scizor still need to be obtained by evolving via items found in the Sevii Islands. So just the 6 left for Kanto now (the Squirtle line) and 19 more Johto Pokémon.

Yesterday I got to only 35 Pokémon away from completing the all genders living Pokédex.
The remaining Pokémon to breed/obtain are: Male and Female Shellder, Cloyster, Scyther and Electabuzz for Kanto version exclusives (8); Female Bellossom, Male and Female Wooper, Quagsire, Murkrow, Slowking, Qwilfish, Scizor, Delibird, Skarmory and Elekid (19) for Johto version exclusives; Suicune (1) to obtain in the second save file; and the Squirtle line and Raikou (7) to obtain in the third save file. I could probably finish off Kanto in a week or two, but the rest might take a little longer.
