Shroom and Gloom Deck Guide: Explore Deck vs Combat Deck Explained

Shroom and Gloom is the kind of roguelike that looks ridiculous at first glance and then quietly eats several hours of your evening. It has mushrooms, cooking, grotesque enemies, hand-drawn visuals, and a first-person dungeon-crawling setup that sounds like it shouldn’t work together. Somehow, it does.

Developed by Team Lazerbeam and published by Devolver Digital, Shroom and Gloom entered Steam Early Access on September 10, 2026. What immediately caught my attention wasn’t just the strange fungal setting. It’s the way the game splits its deckbuilding system into two completely different decks.

You don’t have one deck that handles every problem. You have an Explore Deck for navigating the world and a Combat Deck for killing whatever nasty thing is waiting around the next corner.

That sounds simple until you realize how closely the two systems are connected.

After spending time with this style of gameplay, I think the dual-deck idea is easily one of Shroom and Gloom’s strongest features. It creates situations where a decision that seems harmless while exploring can come back to bite you five minutes later in combat.

And yes, sometimes that means staring at a locked chest while wondering whether smashing your own face into it is actually a good idea.

The Big Idea Behind the Double-Deck System

Most deckbuilders teach you to think about one deck. You add cards, remove bad ones, improve your draw consistency, and gradually turn a weak starting collection into a machine.

Shroom and Gloom takes that familiar formula and splits it in half.

The Explore Deck is about everything that happens outside combat. The Combat Deck takes over when things get violent.

The clever part is that neither deck can really be treated as an independent system.

Exploration determines what resources, upgrades, food, and opportunities you discover. Combat determines how much health you lose, what enemies you can turn into food, and what materials you can use to improve your future runs.

That creates a constant push and pull between greed and survival.

Do you take the dangerous route because it might contain a valuable upgrade? Do you spend health opening something now when you know another fight could be waiting nearby? Or do you play it safe and accept that you’re leaving potentially useful loot behind?

Those are the decisions that make the system work.

The Explore Deck Is More Than a Movement System

The Explore Deck is basically your toolbox.

During a normal dungeon run, you’re not simply walking through corridors looking for the next fight. Your cards determine how you interact with the environment. Doors, obstacles, hidden areas, loot and other objects all become part of the card-based gameplay loop.

This is where Shroom and Gloom feels very different from conventional roguelike deckbuilders.

Instead of thinking, “Which attack should I play?”, you’re often thinking, “What is this room asking me to do?”

Your exploration cards can help with things such as:

• Revealing routes and scouting upcoming areas.
• Digging for hidden loot and potential upgrades.
• Opening locked doors and containers.
• Preparing camps and recovering between encounters.
• Finding resources that eventually improve your Combat Deck.

The result is a deck that feels less like a collection of abilities and more like an adventurer’s backpack.

And honestly, I like that distinction.

It makes the dungeon itself feel more interactive instead of turning exploration into little more than downtime between battles.

Bash Might Be the Most Important Exploration Card

One of the smartest ideas in the entire system is the Bash card.

Running out of keys in a dungeon crawler can be incredibly annoying. Worse, if the game doesn’t give you another way forward, you can end up feeling like you made an irreversible mistake several rooms ago.

Shroom and Gloom avoids that problem.

Bash is effectively your emergency solution. If you don’t have a key or lockpick, you can smash your way through certain obstacles.

The catch?

You pay for it with health.

This sounds like a small gimmick until you’re already damaged and standing in front of a chest that might contain something fantastic.

I’ve always liked mechanics that make you ask whether the reward is worth the immediate cost, and Bash fits that philosophy perfectly. It isn’t simply a backup key. It’s a temptation.

You can always force the issue.

The question is whether you should.

The Combat Deck Plays by Completely Different Rules

Once a hostile mushroom decides you’ve been having too relaxing a day, the game switches over to the Combat Deck.

This is where the purple combat cards come into play, and the entire rhythm changes.

You have combat energy, attacks, status effects, cooking mechanics and ways of transforming defeated enemies into resources.

But there’s one major difference that immediately changes how you approach fights:

Traditional block cards aren’t part of the equation.

That’s a pretty huge departure from games such as Slay the Spire, where blocking can be just as important as dealing damage.

In Shroom and Gloom, the philosophy is much more aggressive.

The basic idea is almost comically simple: don’t spend your entire life trying not to get hit. Kill things, cook them, and eat them.

It sounds absurd.

It also creates some surprisingly interesting combat decisions.

Why the Lack of Blocking Changes Everything

Without conventional defensive cards, every point of health becomes more valuable.

You’re going to take damage.

The goal isn’t necessarily to prevent every hit. Instead, you’re trying to end fights quickly enough that the damage you receive can be recovered through the game’s food and healing mechanics.

This makes the combat system feel much more aggressive than the average deckbuilder.

You might start a fight thinking about damage output rather than defense. Then you begin setting up status effects, weaken an enemy, prepare the killing blow and think about what you can do with the corpse afterward.

That’s where the cooking mechanics become genuinely important.

Kill, Roast, Eat: The Strange Combat Economy

The combat loop can essentially be broken into three stages.

First, weaken the enemy.
Use attacks and status effects to reduce its health while setting up your next moves.

Second, finish it with the right card.
A Roast-style finisher can trigger a Fatal effect when the enemy is vulnerable enough.

Third, turn the corpse into something useful.
Defeated enemies can become Toasties that you can consume for healing, or they can become ingredients for soups and other bonuses.

This is one of those mechanics that looks like a joke in a feature list but becomes much more interesting once you actually think about its consequences.

An enemy isn’t just an enemy.

It’s potentially damage, healing, ingredients, upgrades, or future power.

That gives combat an unusual economy where killing something is only the beginning of the decision.

Explore Deck vs Combat Deck: What’s the Difference?

The easiest way to understand the system is to put the two decks next to each other.

The distinction is important because the two decks reward completely different habits.

With the Explore Deck, I prefer patience. There’s usually value in knowing what’s ahead before spending resources.

Combat is the opposite.

Once you’re fighting, hesitation can become expensive. The longer a dangerous enemy survives, the more opportunities it has to drain your health.

Your Health Bar Connects Both Decks

This is probably the most important thing new players should understand.

Health isn’t just a combat resource. It is an exploration resource too.

If you enter a battle at full health, you have much more freedom to use Bash later.

If you finish a brutal encounter barely alive, suddenly every locked door becomes a problem.

That creates an interesting feedback loop.

Imagine finding a chest behind a locked door. You don’t have the right tool, but you can Bash it.

Normally, the decision seems obvious: take the damage and grab the loot.

But what if you know an elite enemy is likely to appear in the next room?

Now that chest isn’t just a loot opportunity. It’s potentially a terrible investment.

This is where the double-deck design starts feeling less like a gimmick and more like a genuine strategic system.

Exploration Is How You Build Your Combat Deck

The Explore Deck also serves as your route toward stronger combat options.

Digging into suspicious areas, choosing certain paths, finding merchants and exploring optional locations can produce cards, upgrades, ingredients and other resources that improve your combat setup.

That means skipping exploration content isn’t necessarily saving time.

Sometimes you’re simply choosing to enter your next fight with a weaker deck.

Personally, this is one of the aspects I enjoy most. It encourages you to learn the dungeon rather than rushing from one battle to another.

The best route isn’t always the shortest route.

Sometimes the weird side path with questionable mushrooms growing out of the walls is exactly where the upgrade you need is hiding.

Cooking Is More Important Than It Looks

The cooking system ties everything together.

Enemies provide ingredients, ingredients can become soups, and soups can provide longer-term benefits that affect how a run develops.

This makes food vendors and cooking opportunities especially valuable.

I’d rather have a reliable source of useful ingredients than blindly depend on random treasure whenever possible. Consistent upgrades are usually more valuable than a single lucky loot drop.

This also creates another reason to think about your combat targets.

Sometimes the most important question isn’t:

“Which enemy should I kill first?”

It’s:

“Which enemy gives me the best resource when this fight is over?”

That’s a very different way of looking at combat.

The Combat Deck Can Get Ridiculously Powerful

Another feature worth watching is the game’s approach to card evolution.

Certain cards can become substantially stronger as you continue using and modifying them. A card that looks mediocre early in a run can eventually turn into a ridiculous centerpiece for a late-game strategy.

This is where the roguelike progression starts getting addictive.

You find a card.

You experiment with it.

You upgrade it.

You discover a combination you didn’t expect.

Suddenly that card is doing something completely different from what you originally imagined.

For players who enjoy creating absurdly powerful builds, this is likely to become one of Shroom and Gloom’s biggest strengths.

The game clearly wants players to experiment rather than simply follow one predetermined build.

Early Strategies That Make Sense

The community has already started identifying some interesting approaches, although Early Access means the meta will inevitably change.

One particularly notable strategy revolves around enemies that summon weaker creatures. If your build rewards healing, kills or repeated combat triggers, these smaller enemies can potentially become a source of additional scaling.

It’s effective, but there’s a catch.

It can also turn fights into a boring grind.

Personally, I wouldn’t build an entire run around exploiting an encounter simply because the numbers allow it. Roguelikes are at their best when you’re making interesting decisions, not when you’re spending ten minutes farming the same disposable enemies.

A few other principles are more broadly useful:

1. Don’t waste health casually during exploration. Bash is useful, but it shouldn’t become your default solution to every locked object.
2. Look for consistent food and cooking opportunities. Reliable healing and passive bonuses can matter more than a single lucky loot drop.
3. Think about both decks before committing to a route. A great exploration reward isn’t necessarily worth entering combat in terrible condition.
4. Experiment with card upgrades. Some of the strongest builds are likely to come from combinations that aren’t obvious at first.

Characters Can Change How You Build Both Decks

The character archetypes add another layer to the double-deck system.

Characters such as the Paper Boy, Lunch Lady, and Concerned Parent aren’t simply cosmetic choices. Their starting cards can push you toward different approaches to exploration and combat.

For example, a character with strong exploration tools but weaker early combat options may encourage a completely different route through the dungeon.

You might prioritize food, relics and combat upgrades much earlier because you know your starting Combat Deck isn’t going to carry you through difficult encounters by itself.

This is another reason I wouldn’t recommend treating the two decks as separate builds.

Your character effectively changes the relationship between them.

Is the Double-Deck System Actually Good?

After looking at how all these pieces fit together, I think the two-deck concept is more than a clever marketing hook.

The Explore Deck gives the dungeon meaning.

The Combat Deck gives encounters their own identity.

Your health connects them.

Cooking connects enemies to progression.

Exploration feeds combat upgrades, while successful combat gives you resources that make future exploration safer.

That creates a loop where every decision has consequences outside its immediate context.

And that’s exactly what I want from a roguelike.

I don’t need every run to be fair. I don’t need every card to be perfectly balanced. What I want is a game where I can look back at a disastrous decision and understand why it happened.

Shroom and Gloom seems very interested in creating those moments.

Sometimes you’ll open the wrong door.

Sometimes you’ll spend too much health on loot.

Sometimes you’ll enter a fight with a deck that simply isn’t ready.

And occasionally you’ll build an absolutely disgusting combination that turns a terrifying fungal monster into dinner.

That’s the kind of controlled chaos that makes roguelikes difficult to put down.

Final Verdict

Shroom and Gloom’s Explore Deck and Combat Deck are at their best when you stop thinking of them as two separate systems.

The Explore Deck determines what opportunities you find and how much you risk before combat. The Combat Deck determines how efficiently you survive those risks. Your health, food, upgrades and cooking choices keep bouncing between the two.

The result is a deckbuilder that feels noticeably different from the usual formula.

There’s no comfortable defensive shell to hide behind. There isn’t one universal deck solving every problem. Instead, Shroom and Gloom constantly asks you to balance preparation, aggression, greed and survival.

For me, that’s the game’s biggest selling point.

If you’re looking for a traditional card battler, this might feel strange at first. If you’re willing to embrace its weird fungal logic, the double-deck system has the potential to become one of the most interesting roguelike ideas of 2026.

And frankly, any game that lets me turn a horrible mushroom monster into dinner after stabbing it to death has already earned my attention.
