Adventure Cards is the first collectable card game stored entirely on chain. Each NFT includes 45 procedurally generated cards, enough to play a full game.
Inspired by LOOT and MtG, Adventure cards are crypto primitives. You can do anything you want with them. They are free to mint (except... you know... gas)
There are four types of cards: creatures, artifact, enchantments, and spells. You should notice some familiar things in there.
