RULE UPDATE - effective 3/16/2016

Because of the recent patch that enables additional deck slots, we are updating our process for taking screen shots to verify a single playable deck per class. With this update we are also changing our process for communicating bans. We will no longer queue a game with the class we are banning. Instead, we will create an unplayable deck named "BAN" that will communicate the ban through the screen shot process.

Here is the complete new rule that can be found in the official Rules document:
Pre-match Process:
Prior to the beginning of each match, players must complete the following process that will both communicate the ban of each player and verify that only one playable deck exists for each selected class.

1. Before entering the challenge screen, players should communicate with their opponent to confirm that their opponent’s decks are correctly prepared. Correctly prepared decks include:
   1. Only one playable deck for each selected class for the match
      1. Decks that are not complete (contain less than 30 cards and have red “X” over them) are not considered playable.
         
      2. Decks for classes besides the classes selected by the player for that week are not considered payable
   2. A “Ban” deck
      1. The “Ban” deck may not be a playable deck
      2. The “Ban” deck must be named “BAN”
2. Players enter the challenge screen
3. The opponent will send an in-game chat message. A screenshot is taken that shows the available decks and must include this chat bubble from the opponent.
   1. If the player has more than 9 decks (decks on both pages), this process must be repeated for the second page, including the chat bubble.
4. The screenshot(s) are emailed to the opponent before beginning play.
5. Both players must confirm receipt of the screenshot and verification of eligible decks and the ban before beginning play.

If a player bans incorrectly, the opposing player may select their own class to be banned. An incorrect ban includes (but is not limited to): not labeling the “Ban” deck with the title “BAN”, or having a “Ban” deck prepared for a class not selected by the opponent.

If a player has a “Ban” deck that is playable (is a complete deck with 30 cards and of a class that the player is bringing), it will be considered a violation of the 1 deck rule and that class will be prevented from scoring a win.
