I was lucky and got her from my first Heroic Legendary Soul! Then I was going for Ibuki (Gunner Shinobi) and opened 20 normal Heroic Souls and got another Assassin Banshee and...finally Gunner Shinobi...

...but not lucky on the new Eddies, missing all the last ones (IM-Eddie, Virtual XI Eddie, NOTB Eddie, Pharaoh Ramesses Eddie, Samurai Emporer Eddie).
