Ah, the conversation and announcement about that got eaten in the forum crash/reset. Wizards banned several cards for racial and cultural reasons a while back, most notably the infamous Invoke Prejudice. In order to let Old School players play the cards
mechanically without the problematic depictions, an Old School group called the Northern Paladins made mechanically-identical, but re-flavored, versions of the cards:
http://northernpaladins.com/2020/08/19/1229/- Jihad -> Common Foe
- Stone-Throwing Devils -> Dancing Rats
- Cleanse -> Desiccation
- Pradesh Gypsies -> Eiriene of Spring
- Imprison -> Malaise
- Invoke Prejudice -> Psionic Symmetry
- Crusade -> Traveling Party
I could have just removed the cards outright, but I figured it would be neat to replace them with these "New Dawn" versions instead.
