In the last days of December 2022, the [NFT Guys](https://nftguys.biz/) team launched a satirical NFT collection featuring Croats. It started with 1991 NFTs, but due to their dynamic nature, and the burning mechanism, this number will only get lower. It was a free mint on Polygon, and the collection was minted within 48 hours. The NFTs are layered and have a picture within a picture, with the possibility of revealing additional NFTs.

The scarcity and rarity of the collection are dynamic and depend on the actions of the collection owners.

Smart contract functions
------------------------

The collection has three smart contract functions:

*   burnAdvanceMoved
    
*   burnRegressDilute
    
*   burnResurrect
    

**Function 3**, burnAdvanceMoved, take your NFT to a future or alternate timeline.  
Only 400 NFTs can reach this state, and once in this state, there is no return to previous states. The chance of burning tokens is 4/10.

**Function 4**, burnRegressDilute, take your NFT to past times or another nationality surrounding or living in Croatia. You can revert to the initial state, and the chance of burning and losing your token is 2/10.

Additional hidden NFTs

**Function 5**, burnResurrect, return your NFT from the state reached with function 4 to the initial state. The chance of burning tokens is the smallest of all functions, at 1/10.  
Please note that you can not use function 3 if function 4 has already been executed. In this case, function 5 must be completed before starting function 3.
