Site: Dueling Nexus Add new comment Comments Ive tried on multiple devices across multiple wifi and data connections and yet it tells me it could not authenticate. Its been the same sign in since the site began so i want to know what happened to my account. I had some wonderful decks on there and i spent alot of time devising them properly. reply Add new comment Your name * E-mail * The content of this field is kept private and will not be shown publicly.
