I'm looking for a search that captures all sweepers on Scryfall. Simply "Destroy all creatures" misses sweepers such as:
- Languish (gives creatures -x/-x)
- Farewell (exiles)
- Terminus (puts on bottom of library)
- Oblivion Stone (destroys permanents that don't meet a particular condition)
- Hour of Revelation (destroys all nonland permanents)
I'm especially interested in sweepers that can kill planeswalkers.
