For the shadow realm you have one of two choices which are as follows;

- Single Duel;
                 -Both players bet an amount of points that each player can pay.
                 -The winner gains the amount of points and the loser loses that many.
                 -Both player must have the amount of points that were agreed upon.
                 -Latest Ban List Applies.
                 -Must be hosted in Advanced (Unrated).
- Match Duel;
                 -This is the same as the single except in match format.

You must post a screenshot of your win along with proof that it was a Shadow Realm duel. I highly suggest that before picking rock, paper or scissors on Dueling Network, you ask your opponent to confirm in the chat that it is a Shadow Realm, single/match duel and take a screenshot of it and post that along with your win. If a player disconnects or quits during the duel, they will receive an automatic loss. Also, when you win, lose or tie in a duel it will be added to your SR record.

When you manage to collect a certain amount of shadow realm victories you can request a userbar. The milestones are as follows;
