As I've already mentioned; the sealed games Revised, 4th, 5th, 8th and Chronicles selections are controlled by the codes set up in the Manalink.csv 'Expansions Rarity' column. The game doesn't randomise the selection of these sets - 'somebody unknown' set up the current codes for what appears to be a fairly random section of cards.
Taking on board what you said about the Rarity.csv - even though the game looks for this file, it would seem it doesn't actually reference the file any more for what could be regarded as the 'fixed sets' in the Deck Builder (Those with their own filtering buttons - The Dark, Legends, Antiquities, Arabian Nights, Astral, and Unlimited - now combined with Revised and 4th).
These sets were originally controlled by the Rarity.csv 'Coded?', 'Original Set' and 'Rarity' columns.
Whereas, Revised, 4th, 5th, and Chronicles all have separate columns in the Rarity.csv file, which determines their set and rarity in a single column - unlike the earlier set filtering system using two columns with a named set entry and a rarity code.
When Mok migrated all the information from the Rarity.csv file to the manalink.csv, the 'Original Set' column became what we now know as the 'Expansion' column with a 4-digit code replacing the named entries, the 'Rarity' column was ported using the same name with a 1-digit code, and the 'Revised', '4th', '5th', and 'Chronicles' columns were combined into what is now the 'Expansions Rarity' column using a 5-digit code.
The SkyMagic editor lists the codes for the manalink.csv 'Expansion', 'Rarity' and 'Expansions Rarity' column codes as the following: (The codes for '8th Edition' were added later.)
'Expansion' (Manalink.csv) = 'Original Set' (Rarity.csv)
0800h - Unlimited
0004h - Arabian Nights
0002h - Antiquities
0100h - Legends
0020h - The Dark
0008h - Astral
0040h - 8th Edition
01000h - Tokens
0080h - N/D
Rarity (Manalink.csv) = 'Rarity' (Rarity.csv)
1 - Common
2 - Rare
4 - Uncommon
3 - Astral / Promo (added later)
'Expansions Rarity' (Manalink.csv) = '3rd Ed.(Revised)', '4th Edition', '5th Edition', 'Chronicles' (Rarity.csv)
1st digit - 8th Edition
2nd digit - Chronicles
3rd digit - 5th Edition
4th digit - 4th Edition
5th digit - Revised
0 - Unavailable
1 - Uncommon
