Your Main Deck can include up to 3 copies of the same named card. 1. This includes your Chosen Champion. Example: A deck could include Volibear, Furious as its Chosen Champion and still include 2 more copies of Volibear, Furious. 2. Cards have different names even if they represent the same character. Example: A deck could include 3 copies of Yasuo, Remorseful and 3 copies of Yasuo, Windrider, because they have different names.
