Core problem: There is no block. You take hits. Explore is your sustain and your upgrade engine. The deck swap is the whole game: spend Explore before you commit to the next doorway, because Explore energy does not carry over into Combat.

1How the Two Decks Interact

The swap is the whole game. Spend Explore before you commit to the next doorway.

4Key Decisions

ChoiceWhat players do
Heal now vs upgrade nowUpcoming elite or boss and you are not full: rest or food. Healthy and you have Dummy in hand: Dummy first. A plus 2 on a fatal card pays more than 9 HP.
Key vs BashKey is free and consumes the card. Use on the lock that gates a reward, not every decorative padlock. Bash pays HP. Fine if you have overheal and want to keep a key for later.
Add a Combat card vs thin the deckShovel adds cards. Good early, bad if Combat is 20+ unfocused hits. After 1 or 2 scaling weapons, start removing or evolving weak Stabs instead of digging every X.
Eat in fight vs save food for ExploreEat in fight if you will die this turn. Save a Toasty if Explore has an eat-to-grow chain like Everlasting Truffle plus Fruiting Limb.
When to slim ExploreExplore with 12+ one-off tools bricks Dummy and Rest. Consume keys, exhaust spent shovels, forget dead cards at frog spots. Explore wants repeatable engines, not a junk drawer.

5Combos Players Actually Posted

Max HP Engine (Explore)
Well Knitted + 0-cost heal
Heal-over-max raises max HP. Play the 0-cost heal with Well Knitted in hand to redraw the heal and grow max HP for 0 energy. Add draw and free energy and you can loop Dummy forever. This is how people posted 500+ HP demo clears. Do not force it if the pieces do not appear.
Eat-Scaling Combat
Everlasting Truffle + Fruiting Limb + Vicarious Mace
Damage on eat and damage when another weapon grows. Players reported both weapons in the 600s when the loop did not brick. Energy dump: a card that exhausts for energy plus a damage card. The pattern is an Explore card that refunds itself plus a Combat card that grows when you eat.
