Cards of Ethernity

Cards of Ethernity is a collectible card game built around on-chain ownership, with cards issued across Avalanche, BNB Chain, Ethereum and Polygon rather than a single network. The cards represent creatures, spells and items, and the systems described go beyond simple collecting: levelling individual cards and combining them into stronger versions, plus tournament play as the competitive outlet. It is also tagged as an AR title, which suggests the deck is meant to be experienced outside a plain browser client, though the material available says little about how that layer actually works in play.

What is clearest here is the ownership and progression side. Cards are stored on-chain, so scarcity and transfer are handled by the ledger, and the merge-and-upgrade loop gives collectors a reason to hold duplicates instead of dumping them. What is much less clear is everything a card player would want pinned down before committing: no developer is named on the listing, and the available description leans on tone — stunning artwork, a vibrant community — where it should be explaining card acquisition costs, tournament reward structures or how multi-chain assets relate to one another.

It suits players who already trade NFTs and want a card game where assets move between chains. Anyone who wants concrete rules and economics before buying in should read the project's own site at coe.gg first.
