Roguelike Deckbuilder Glossary: 25 Terms That Confuse New Players

Deckbuilder vs CCG: the core difference

A collectible card game (CCG) like Hearthstone or Magic: The Gathering has you build a deck before you play, then take that same deck into match after match. You might tweak it between games, but the core cards stay yours.

A roguelike deckbuilder starts you with a small basic deck every single run. You add cards, remove cards, and reshape the deck as you go. The deck is temporary. It lives and dies with the run. That changes everything about how you evaluate a card. A 7-cost finisher is unplayable in your opening hand, but it might win the game if you build your entire run around surviving until turn three.

• Draft, picking one card from a random set offered after a fight or event
• Thinning, removing weak starter cards so your good cards show up more often
• Scaling, damage or block that grows each turn (poison stacks, strength buffs, etc.)
• Cantrip, a cheap card that draws another card, keeping your hand size up

Permadeath, meta-progression, and what carries over

Permadeath means your run ends completely when your health hits zero. No continues, no loading a save. The deck you spent forty minutes building is gone.

Meta-progression is what the game lets you keep. Some roguelike deckbuilders unlock new cards for the pool, new characters, or difficulty modifiers. Others keep almost nothing. The tension between "this run is temporary" and "I am slowly getting stronger across all runs" is the emotional engine of the genre.

I find the best meta-progression feels like expanding your toolkit, not your stats. Starting with more max health every run just makes the game easier. Starting with a weird new card in the pool makes every future run different.

• Run, one complete playthrough from start to death or victory
• Unlock, a new card, relic, or archetype added to the possible pool for future runs
• Ascension / Difficulty tier, a harder ruleset unlocked after a win, stacking new penalties
• Seeded run, a run generated from a specific code so you or others can replay the exact same layout

Relics, potions, and consumables

A relic is a permanent passive item you pick up during a run. It might make your first attack each turn deal extra damage, or let you draw a card when you block, or change a core rule entirely. Relics are the wildcards that break a run wide open. Two cards that were mediocre alone can become a machine with the right relic.

Potions are one-use consumables. You usually carry a small number and can drink them mid-fight for healing, damage, or a temporary buff. The skill is knowing whether to save them for the boss or use them now so you do not die before reaching the boss.

Some games also have single-use scrolls, bombs, or food items. The principle is the same: limited resources that reward planning and punish hoarding.

• Boss relic, a powerful relic earned by defeating a boss, often with a trade-off
• Synergy, when a relic and a card (or two cards) combine to produce a stronger effect than either alone
• Proc, short for "procedure," when an effect triggers automatically from a condition
• Charge / Stack, a counter on a relic or card that builds up until spent for an effect

Elites, bosses, and the difficulty spike

The map in a roguelike deckbuilder branches between different encounter types. A normal fight is the baseline. An elite fight is harder and gives better rewards. A boss fight is the gate you must pass to advance to the next section.

Elites are where you test whether your deck actually works. A deck that stalls and heals might crush normal fights but time out against an elite's scaling damage. A glass cannon might kill the elite in three turns or die on turn two. The elite tells you the truth.

Bosses usually have patterned behaviors, multiple phases, or unique mechanics that punish specific strategies. The first time you face a boss, you learn what it does. The second time, you build to beat it.

• Minion / Add, a smaller enemy that accompanies a boss or elite
• Phase change, when a boss hits a health threshold and changes its behavior or resets a buff
• Telegraph, an attack that warns you one turn ahead, letting you prepare block or a counter
• Scaling enemy, a foe that grows stronger each turn, forcing you to end the fight quickly

Archetypes, classes, and why they matter

An archetype is a coherent set of cards that share a mechanical theme. One archetype might focus on huge single hits that cost a lot of energy. Another might play many free or cheap cards in one turn. Another might stack debuffs on enemies and let them tick down.

In some games you pick a class at the start and that locks your card pool. In others you start neutral and commit to an archetype by the cards you draft. Both approaches create the same puzzle: do you go deep on one archetype, or spread across two for flexibility?

Going deep gives you the most powerful synergies. Spreading gives you consistency when the random draws do not cooperate. Most good runs do both: one main archetype, one secondary for backup.

• Splash, adding a few cards from a secondary archetype without fully committing
• Pivot, abandoning your early draft direction when better cards appear for a different archetype
• Engine, a loop of cards that generates more resources than they cost, letting you play indefinitely
• Exhaust, removing a card from your deck for the rest of the fight, sometimes for a powerful one-time effect

Roguelike deckbuilder mechanics: map events and alternate paths

The map itself is part of the strategy. A shop might save a dying run if it sells the exact card you need. A random event might give a free relic or curse your deck with a useless card. Dice battles, puzzle rooms, or wager encounters break up the fighting and let you convert health or gold into other resources.

Some paths are riskier but offer better rewards. Some are safe but slow, letting enemies scale past what your deck can handle. Reading the map and planning your route is as important as playing your cards well.

I wrote a longer piece on how to spot and commit to synergies during a run. How to Build Synergies in Roguelike Deckbuilders: A Practical Framework walks through the decision tree I use.

• Branching map, a web of paths where you choose your next encounter from several options
• Dice battle / Event, a non-combat encounter using a different resolution mechanic
• Shop, a place to buy cards, relics, potions, or removal services
• Shard / Token, a persistent currency earned across runs, often for cosmetic or meta-unlock purposes
• Wall archetype, a defensive playstyle built around block, thorns, and outlasting enemies
