Hey Riftbounders, 


Vriss here with the Tournament Rules update for Vendetta. This update brings a few major changes so let’s dive right in!

Full Tournament Rules Doc : [Tournament rules doc link]

Increasing Sideboard Size to 10

We’ve been very happy with the amount of diversity in the Riftbound metagame. As more and more cards and Champion Legends get added, we expect variety to continue to grow. We are giving players more opportunity to strategize and react to the different decks they might face by increasing the maximum sideboard size from 8 to 10. Vendetta is the perfect opportunity for this change, bringing more designs aimed at giving players powerful sideboard options.

Acknowledging Triggers and Public Information Changes

Communication and mutual understanding between players is crucial during a game of Riftbound. To reinforce this, we clarified what it means to “acknowledge” a trigger or a change to public information during gameplay. To fully acknowledge these moments, you must make sure to communicate them to other players at the table.

Tracking Resources

While there were clear guidelines for tracking score, we determined there was a lack of clarity on tracking resources such as XP and floating Energy/Power. We’ve updated the tracking section of the Tournament Rules to include guidelines for when and how you need to track resources like these during a game.

Asking Judges Questions

We updated the wording around the guidelines for what a floor judge can answer during a high OPL match of Riftbound. We removed “hypothetical” from the description, as it was causing more harm than clarity for both judges and players.

We do not expect players to have an encyclopedic knowledge of all of Riftbound’s rules. One of the many roles of judges is to help players understand those rules, especially when obscure scenarios arise during a game.

Judges can answer questions during a match that are not related to the strategy of the game or specific actions taken in the game. They can answer rules, card text, or policy questions, but not strategic ones. 

All of that being said, the goal is for judges to be able to help players as much as possible without hurting competitive integrity. In most scenarios, judges can help guide players to ask the right questions to clarify the rules as written without getting into strategy for the current game.

Disciplinary Code

This new section is expanding on the core values that were already present in the Unsporting Conduct section. For players attending events, this should not have a meaningful difference on your experience and is just aligning Riftbound with similar systems to all of Riot’s Games.
