You can now use the in: or wasin: keyword to filter cards based on a set they “appeared in”, but not otherwise require that set in results.
Examples of interesting searches you can make with this keyword:
- Cards that were in both Alpha and Eternal Masters
- Homelands cards have been printed online
- Cards that were in Alpha, but not Revised
- Cards in both Amonkhet and Amonket Invocations
Previously this functionality was available using the e:set+set or e:set,* syntaxes. Use the in: keyword instead for official support.
