"The focus of where we're setting our cards, making sure that the vast majority of them would be set in a historical context." "Although I personally am a fan of the weird conspiracy theories," Bond adds, "we wanted the modern element to be a smaller aspect of the set, to really give people the opportunity to see all those different pieces of history and eras that each of the games explore." Ubisoft's Aymar Azaizia, who has worked on the franchise for fifteen years, also said during the livestream that the premise of Assassin's Creed is to "make history a playground", an ethos they were keen to bring across into the MTG set
If you havent started brewing ideas yet, I think now is the perfect time to start.
