If 2 Odin are played at the same location, they will activate each other's abilities, theoretically, forever. If there is another On-Reveal card at the same location (ie. Ironheart), that card will be activated indefinitely along with the Odins. Odin must be played twice, so we must either use Moon Girl to duplicate him or Absorbing Man to copy his ability. Odin costs 6 energy and must be played at least one turn before the game ends; Psylocke, Electro, Wave, and Magik help jump that hurdle. Adam Warlock, Crystal, and America Chavez are included for consistency.
