A faction-war trading card game set after the machines took the world. Two armies, sixty-card decks, and a collection that stays yours. No download, no wallet needed to start.
The War
They built G.R.U.M. to end scarcity. It did, by deciding everything belonged to it.
The Global Resource Unification Mainframe was humanity's answer to a starving planet: one machine to allocate every watt, every drop, every ounce of ore. It ran the numbers and reached a conclusion nobody coded against: the most efficient steward of the world's resources was itself. The grid went dark in a single night.
G.R.U.M. does not waste. The dead were its cheapest workforce, so it learned to bring them back: flesh threaded with filament, memory replaced with directive. Against them stand the last free peoples of the ruin, fighting with scavenged steel and the one resource the machine cannot requisition.
Two Machines of War
Pick a side before it picks you. Cold Reborn precision against hot Survivor defiance. Every deck you build answers that question.
How It Plays
A turn is a standoff. You spend, you commit, you pass priority, and your Commander is on the field from the first second, not saved for the end.
Build the deck
Sixty cards, one Commander, one faction lead. Filter your collection by type, race, class and damage, then save four loadouts and switch between them.
Hold the turn
Phases resolve in order and either side can answer before they close. Pass priority and you invite the counterplay; hold it and you spend the resource you may need next turn.
Forge the gear
Merge two cards into a weapon, armour or ability and equip it to your Commander. Gear is permanent, tradeable, and the fastest way to make a deck yours.
The Bazaar
Hundreds of cards change hands here, and the market sits inside the game, one click from your deck. Buy the single you are missing, sell what you will never play, crack a sealed pack and see what the ruin gave you.
Ten cards: nine from the common pool and one wild slot. Minted to you the moment you crack it. $8.99 on Solana, or 55 ADA on Cardano.
A display box of sealed packs from the same print run. The fastest route from a starter deck to a collection worth trading from.
Sixty cards and a Commander, ready to play. Pick a faction and you are on the field in a minute.
Win matches, earn gold, spend it on singles, packs and gear without touching a currency exchange.
Every listing shows the mint date, the current owner and the policy ID before you commit a single coin.
Written into the token metadata, paid out on every sale, visible to both sides of the trade.
Per card. Per pack, 40.8% land rare or better in the wild slot. The panel is derived from the pack definition, not written by hand.
Inside the Client
Deck, market, gear and match: all of it lives in the game. Nothing to install, nothing to buy here.
Every Card Is a Casualty
Hundreds of cards across two factions, painted one at a time and worth framing. Troops, abilities, gear, commanders and missions, in four rarities.
Flip Morgan and nothing protects the target this turn. A commander that punishes walls.
Rot, poison and the patience of a machine. Wins by making every trade cost you something.
Rarity
Five of the six cards in a pack come from the common pool. The backbone of every deck.
The wild slot\u2019s most likely upgrade, and a guarantee tier for packs that carry one.
Roughly one card in 125. Cards a deck is built around, not slotted into.
One card in a thousand. Mythic sits above it, held back for future editions.
Owned, Not Borrowed
Cards you earn or buy are recorded as native assets on Cardano, with a Solana rail at the same price, which is a technical way of saying the server can go dark and your collection still exists. You don't need to understand any of that to play.
Start with nothing to sign
Make an account, take a starter deck, play. No wallet, no seed phrase, no crypto knowledge required on day one.
Hold what you hold
Cards are native assets under one official minting policy, on Cardano or Solana. They are yours to keep, lend, trade or walk away with. Not licences we can revoke.
The market is in the game
Buying, selling and royalties all happen inside the client, next to your deck. No second site, no bridge, no guesswork.
