Hell Deck Feed your demons to win

Your units do not stand politely in formation. They hunt each other. Power comes from cannibalism: place a predator next to prey, or feed a card to a hungrier one, and the survivor mutates into something far worse. A feeble grunt can end a run as an apex predator if the chain is built right. Accidental placements count too, so a careless drop can trigger a mutation you did not plan and now have to live with. The store calls this Ecosystem Deckbuilding, and it is the heart of the game: you are not collecting cards so much as engineering a bizarre, twisted ecosystem where survival is bought with flesh.

Space is the real enemy. The battlefield is a strictly limited tile grid, and every placement can set off an uncontrollable chain reaction, for better or worse. You manage your hand, keep an eye on the inventory bag, and try to orchestrate a synergy that wipes out hundreds of oncoming angels at once. There is no room for everything, so every card you keep is a card you chose over something else. Battles play out largely on their own once your pieces are down, which makes this a low-pressure fit if you want strategy without twitchy inputs: the thinking happens before the fight, in what you allow onto the grid.

Each run is short, and death is part of the experiment. A mysterious, omniscient voice watches your failures and promises to fix you each time you break, and returning to the lobby earns permanent upgrades. Because the cards, placements and mutations shuffle differently every time, no two runs play out the same way, and the game is built to be replayed: short sessions, many builds, branching outcomes. When a run collapses, the itch to start again is immediate. Fair warning: luck plays a big hand in which cards show up, so some runs stall no matter how well you plan. Treat each one as a fresh experiment and it stings less.
