Many older sets have been renumbered to more closely match the standardized color/name order that newer sets usually have.
Note that none of the following sets have official collector numbers, so our re-assigned numbers continue to be chosen “arbitrarily” and/or not from WOTC:
- Limited Edition Alpha (lea)
- Limited Edition Beta (leb)
- Unlimited Edition (2ed)
- Revised Edition (3ed)
- Legends (leg)
- Fallen Empires (fem)
- Fourth Edition (4ed)
- Chronicles (chr)
- Homelands (hml)
- Fifth Edition (5ed)
- Portal (por)
- Portal: Second Age (po2)
In addition, the following sets were renumbered to match either the partial or full list of collector numbers we have for that set from Magic Online. The rest of the set numbers were assigned “arbitrarily” as with the above list.
