Cards whose art, text, name, or combination thereof that are racially or culturally offensive are banned in Primordial.
In short (about the recent WotC article “DEPICTIONS OF RACISM IN MAGIC”), Primordial will work in “autopilot mode” and the cards “whose art, text, name, or combination thereof that are racially or culturally offensive” will also be banned here (like what is done for cards referring to “playing for ante”, although the subject is less serious, I grant you).
