Build the deck mid-run, lose the deck on death, and learn that adaptation is the whole skill.
Deckbuilder roguelikes fuse run-based structure with deck construction, creating games where every card reward, relic, and route choice changes the build on the fly. They live on synergy discovery and tactical flexibility. You are not piloting a deck you perfected last night. You are inventing one under pressure.
Example
Slay the Spire defined the commercial template, Monster Train and Griftlands diversified it, and Balatro proved the subgenre still has room for massive surprise hits.
Why it matters
This subgenre became a modern indie staple because it combines massive replayability, strong spectator appeal, and unusually high strategy density for relatively lean development cost.
