Opponents of this card are usually concerned about new, powerful designs homogenizing the Commander format, and Archaeomancers Map is definitely an efficient enough card to be a talking point in that conversation
Freerunning isnt as busted as it might seem, but its pretty powerful, and an Ezio EDH deck potentially has access to every assassin in the game
