As usual, thanks to everyone reporting in the missing printings thread and in support tickets.

New cards and editions
- imported Mystery Booster Commander Edition
- The List: added the 482 cards reprinted for Mystery Booster Commander Edition, and the 69 cards of the Secret Lair Commander decks Hatsune Miku and Odds & Ends
- Extras: The List: added the 18 double-sided tokens of those two decks, like Tentacle // Illusion and Phyrexian Minion // Angel
- added Chronicles Foreign Black Border, the 125 Japanese black-bordered Chronicles cards
- added Duel Decks: Mirrodin Pure vs. New Phyrexia, listed with the other Magic Online printings
- added Final Fantasy Japanese Promo Tokens, the 10 Japanese-only tokens by M.Ezuka
- added the missing double-sided tokens Robot Hero // Villain, Clue // Emblem: Ob Nixilis of the Black Oath and Warrior // Emblem: Wrenn and Realmbreaker, the Reality Fracture Ability Punchcard and the 2024 resale promo Patrician Geist
- Unhinged Alternate Foils: added the 8 missing ones, like Greater Morphling and Old Fogey
- Foreign Black Border: added the German Forest misprinted with the Plains art

Cleanups
- 637 printings that exist in both foil and nonfoil had one price mixing the two, like the MagicFest Sol Ring, many tokens and Commander deck cards from 2019 to 2023. They now have separate foil and nonfoil prices; copies you marked as foil get the foil price
- Rinascimento, Renaissance and various other older promos should get up to date pricing info
- 927 older promos, like Friday Night Magic, Judge, Arena League and prerelease ones, now show the rarity printed on the card instead of "Special", like all newer promos. Special stays for cards printed with it, like the Time Spiral timeshifted cards and the Kaladesh Inventions
- removed 68 prerelease printings from Kaladesh to Core Set 2020 that were never made, and the 16 double-faced cards from Promo Pack: Strixhaven
- Promo Pack: Core Set 2020: Corpse Knight, Disfigure, Flame Sweep, Negate and the five basic lands were listed twice, they are now only in Promos: Core Set 2020
- Starter 2000: the 27 cards with the Sixth Edition symbol are the same cards as in Sixth Edition, they are now only listed in Classic Sixth Edition
- removed the Planeswalker Deck Alternate Art edition, its planeswalkers are listed in Kaladesh and Aether Revolt
- Magic Premiere Shop: the 2007 to 2010 lands were listed twice, once for the foil, each is now a single printing in foil and nonfoil
- fixed the Insect // Treasure token from Heads I Win, Tails You Lose showing the wrong Treasure art
- 27 cards had a wrong converted mana cost, like Ancient Stone Idol listed with 1 instead of 10
- lands, tokens and other cards that are not spells no longer match a mana cost filter of 0

Other fixes
- searching for card names with periods, like A.I.M. Bot, works now
- card pages and trading opportunities now count the active traders who have a card (seen in the last 3 months and open to trading)
- filtering trading opportunities by specific cards now lists everyone who has them and shows how many active users do, and filtering by many cards is fast again

Thanks Sebi, the search for cards with periods in their names is a blessing!

Amazing... thank you so much for all of this!
