Hi @willowBySword,
Thank you for bringing this issue to our attention!
I found a rule from this link:
While this identity card is in play (in any form), other characters with the title Angel or Archangel and the subtitle Warren Worthington III cannot enter play.
Based on this rule, it seems that you cannot play “41003” since it has the title “Angel” and the subtitle “Warren Worthington III”. And I will also update the coexist code to ensure that players cannot play “41003” when “42001a” is in play.
If you have any further questions or need additional clarification, please feel free to comment.
