# Secondary Marketplace

**Official MagicEden Collection Link:  \[insert link here]**

TR00PS may be bought and sold at anytime during the **GRID WARS.**

We recommend buying and selling **TR00PS** during the Ceasefire [periods](/how-to-war/gameplay/battle-schedule.md).

**WARNING: If you purchase a TR00P in the middle of a Battle, outside the Ceasefire period, there is chance that the TR00P has already been deployed on the Grid. You will inherit the Grid placement and will be unable to change it for that round.**

### **Metadata Updates**

At the beginning of each Ceasefire period, we will update the Status (dead/alive) and Trait Earned for TR00PS on-chain. At the same time, we will also submit a metadata update to MagicEden to update their Trait filters.

All **TR00PS** that died will be unindexed from the official collection on MagicEden. They will be added back into the collection if they are [**REVIVED**](/how-to-war/gameplay/ceasefire/revive-and-bury.md#revive)**.**

All **TR00PS** that survive will earn a trait which will be reflected on-chain and on MagicEden. If you **REROLL** a trait, it will not be finalized onchain and MagicEden until the end of the Ceasefire period, when the next Battle begins.
