If PR(Magnolia) rotates out and gets replaced by PR(Professor Oak), will the Magnolia version still be legal? Or will the players be forced to buy a new playset, because a small italic subtext was changed?
This was answered in the link that I posted:
"From now on, instead of giving the card a new name each time, the name Professor's Research will be used. If the card is updated in the future, the new professor's name will appear in the upper-right corner of the card, but the card name will remain Professor's Research."
The name of the card is "Professor's Research". The name of the professor is not part of the card name and is just flavor text. The Juniper version is called "Professor's Research" and the Oak version of this card is called "Professor's Research". Similarly, Giovanni is just flavor text for the card "Boss's Orders"; the Lysandre version is named "Boss's Orders". If we get a Cyrus or Ghetsis version of this card one day, it too will be named "Boss's Orders."
This is being done to avoid the issue that we had before with different professors having the same effect and having to update the rules because of this. Now it doesn't matter (except in Expanded).
