Plan the next run
Shroom and Gloom deck builder
Plan your Demo combat and exploration decks, keep Foresights separate, and share the combination you want to try.
This builder uses Steam Demo build 23718635. For the paid game, start with the Early Access guide.
How to build and share a Demo deck
- Search by a card name or effect, then select Combat, Exploration or Foresight to narrow the library. Add the cards that form your plan.
- Review the separate deck lists. Change quantities for identical copies and remove cards that do not contribute to the plan.
- Give the deck a name. Your draft saves in this browser; opening the site on another device does not transfer that local draft.
- Choose Copy deck link to share the current plan, or Download deck to save a JSON copy. Copy a fresh link after making changes.
Start with a small core
Choose a core below, then adapt it to the cards available in your Demo run. Copy your current deck link before opening a different core.
- Roast & Scavenger Blade core · Read the play order and conditions
- Exploration recovery core · Read the play order and conditions
What the deck builder keeps track of
The builder organizes cards and quantities. It does not simulate fights, predict draw order or guarantee that a combination is obtainable in your run. Check energy costs and trigger requirements in the Demo card library before committing to a plan.
A shared link contains the deck at the moment you copied it. Later draft changes do not update that link. Keep differently upgraded copies separate when recording a run, and use Record a run to add the outcome and final values.
