# 10.1. NFT Products
**NFT Commanders:**
As Commanders age, they will become more valuable than the others, and upgrading them will be crucial. As players continue to play and upgrade their Commanders, their value will increase, and so will their price. Players will be able to rent powerful Commanders for a few games at auction or buy them permanently to use in Ranked PvP. Each Commander is uniquely created by the system.
**Cards:**
Players can also auction off their cards. When they receive cards *(Unit Cards, Event Cards, Hero Cards, Weapon Cards)* from booster packs or earn them through missions, they can put them up for auction.
Through auctions, Marketplace will be a viable method to acquire specific cards.
**Battle Boards:**
Battle Boards define battlegrounds upon which Storm Warfare matches are played. Battle Boards are based on historic moments and iconic battlefields of WW2.
Once equipped with a deck, the player will be able to combat enemy Zero planes over the endless blue of the Pacific, reenact the greatest tank battle in history at Kursk, and play matches in other key moments of WW2 history.
**Card Backs:**
Card backs are the most artistic cosmetic in the game, as they represent the player's approach to their decks. Card backs can be earned through the Ranked PvP mode, bought from the Store or through other players from the Marketplace. They also come with unique animations as well.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.stormwarfare.com/ecosystem/games/stormwarfare/10.-card-market-and-nft-system/10.1.-nft-products.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
