Muzzle Run incentivises players who manage to own entire collections and subcollections with free tournaments awarding Matic prizes. ### Collection Facts * View which cards you have collected and still need to collect from the [Collections tab.](https://app.muzzle.run/collections) * You do not need to own a Racer of every generation to be considered to own an entire collection. For example, if you own an "Allan" with box preference 1 you do not need to collect any other Allans with different box preferences to complete your collection. * There are ongoing tournaments for kennels who manage to collect different collections and subcollections. [View the tournament tab ](https://app.muzzle.run/tournaments-list)to see what's running next. ### Example The user below needs to own an Andrew Racer with any shirt number (generation/box preference) to own the entire Very Rare subcollection.
