# Deck Building

Like other CCGs, card collection and deck building are some of the most important aspects of Diamond Hand: Legends. Card packs containing a random selection of cards can be purchased. Individual cards can be bought from or sold to other players through the in-game marketplace and Solana exchanges. Diamond Hand: Legends is free to play and play to earn.
