# Collection

**Collection** is a system where you can utilize your spare Relic cards. By registering a [**Relic card**](https://eos-gold.gitbook.io/eos-gold/web3-game-guide/my-page/inventory/relic-card) at the Collection menu, you can receive a boost in your Ruins Run gameplay that scales with the stats of the registered Relic card. The type of boost will vary depending on the season.

A Relic card that is currently registered in the Collection will not appear in your inventory. To enchant or recover a Relic card currently in the Collection, you’ll need to remove it first. You can unregister or swap the registered Relic card with another for a small EGG cost, so make sure to strategize carefully on which Relic card to keep in your Collection!
