The Merge Collection reportedly has a built-in scarcity mechanism to ensure that the supply of tokens decreases over time. Each Merge token transfer merges with the token in the recipient’s wallet, adding up the mass value and resulting in a single token. 

As an example, suppose someone has an NFT Merge, which is m(100), if they buy another NFT Merge, which is m(20), then they will have an NFT Merge m(120), which simply shows that everything has merged automatically. 

All NFT Merges are dynamically generated based on the total mass of the NFT. An NFT will become visually larger as the same owner acquires more mass.
