The best damage cards in Decks of Dexterity are not single high-power attacks, but engine-building cards like Thousand Cuts and Unseen Threat that scale infinitely with the Combo and Mark mechanics. Mastering these two synergies is the non-negotiable key to dealing astronomical damage and melting bosses in a single turn. Forget about clunky, high-cost attacks; true power in this game comes from playing many cheap cards that build upon each other.
This guide breaks down the exact cards, relics, and strategies required to build the ultimate damage engine. We'll move beyond a simple list of "good cards" and show you how to assemble a synergistic deck that can reliably clear the highest floors and trivialize the game's toughest encounters, from the Stone Sentinel to the Void Lich.
Understanding Your Core Damage Mechanics
Before you can pick the right cards, you need to understand the two fundamental mechanics that enable infinite scaling: Combo and Mark. Nearly every dominant damage strategy revolves around abusing one or both of these systems.
The Combo Counter: Your Primary Scaler
The Combo counter is a temporary value that increases by one for every card you play in a single turn. It starts at zero at the beginning of your turn and resets at the end. Certain cards, known as "Finishers," have effects that scale directly with your current Combo count. For example, a card might deal "1 damage for each point of Combo."
The core strategy is simple: play as many low-cost cards as possible to inflate your Combo count before playing a powerful Finisher. This is why cheap card draw and energy generation are critical. A hand full of 2-cost attacks is far weaker than a hand of 0-cost and 1-cost cards that let you cycle your deck and build a Combo of 20 or more before unleashing your final attack.
Mark Stacks: Exponential Damage Growth
Mark is a debuff you apply to enemies. Each stack of Mark causes that enemy to take a percentage of additional damage from all attacks. Unlike Combo, Mark is a persistent debuff that stays on the enemy until combat ends (unless they have a specific cleanse ability). Applying Mark doesn't deal damage directly, but it's the ultimate damage multiplier.
An enemy with 10 stacks of Mark might take 50% more damage from every hit. This makes multi-hit attacks devastating. A card that hits 10 times will get the damage bonus on every single one of those hits. The synergy is clear: build a high Combo count to power up a multi-hit Finisher, and unleash it on a target with a high stack of Mark for truly absurd damage numbers.
The Triumvirate of Top-Tier Damage Cards
While many cards contribute to a winning run, three stand out as the pillars of nearly every elite damage build. If you see one of these, especially early on, it's almost always the correct choice.
Card #1: Thousand Cuts (The Combo King)
Thousand Cuts is a 1-cost Attack that reads: "Deal 1 damage to a random enemy for each point of Combo. Exhaust." At first glance, this seems weak. But its power lies in its ability to turn a high Combo count into a screen-clearing wave of damage. In a deck built around cheap cycling, it's not uncommon to build a Combo of 30 or 40. Suddenly, this 1-cost card is dealing 30-40 damage, often spread perfectly to clear out weaker minions before you focus on a boss.
Its upgraded version removes the "Exhaust" keyword, which is a monumental leap in power. Being able to play Thousand Cuts multiple times in a single turn, with your Combo count growing between each play, is how many record-breaking damage combos are achieved.

Card #2: Unseen Threat (The Mark Setter)
This 0-cost Skill card is the cornerstone of the Mark strategy. It reads: "Apply 3 Mark. If the enemy is above 90% health, apply 6 Mark instead. Exhaust." Because it costs zero energy, it's a completely free way to start multiplying your future damage. Playing this as your opening move against an elite or boss is fundamental.
The upgraded version increases the stacks to 5 and 10, respectively. Landing a 10-stack Mark on a full-health boss for zero energy is the single most powerful opening move in the game. It ensures every subsequent attack for the rest of the fight is amplified significantly.
Card #3: Blade Dance (The Finisher)
If Thousand Cuts is for clearing the board, Blade Dance is for deleting a single target. This 2-cost Attack is the quintessential Finisher: "Deal damage equal to your Combo count. If the target is Marked, this attack hits two times." The synergy is self-evident. You use cheap cards to build your Combo, apply Mark with Unseen Threat, and then unleash Blade Dance.
Let's do the math: You have a Combo of 25. The boss has 10 stacks of Mark from an upgraded Unseen Threat (let's say that's a +50% damage bonus). You play Blade Dance. The first hit deals 25 base damage, which is amplified to ~37 damage by Mark. The second hit does the same. That's 74 damage from a single card play, powered by a setup that cost you little to no energy. This is how you achieve one-turn kills.
Building the Ultimate Damage Engine: A Step-by-Step Guide
Finding the cards is one thing; building a deck that can use them consistently is another. Here’s how to approach your run, floor by floor.

Early Game (Floors 1-5): Prioritizing Card Removal and Key Commons
Your starting deck is bloated with basic Strikes and Defends. Your first priority is to remove these. Visit every shop you can to pay to remove cards. A smaller, more consistent deck is infinitely better than a large one.
Look for common cards that help you cycle:
- Flicker (0-cost Skill): Draw 1 card. The bread and butter of any combo deck.
- Twin Strike (1-cost Attack): Deal 3 damage two times. A solid early damage card that also benefits from Mark.
- Anticipate (1-cost Skill): Gain 5 Block, draw 1 card next turn. A decent defensive option that doesn't stop your engine.
Your goal is to survive while thinning your deck and grabbing any of the Triumvirate cards if they are offered.
Mid Game (Floors 6-10): Hunting for Your Core Uncommons and Relics
This is where the build comes together. You should be aggressively pathing toward Elite encounters to hunt for relics. The right relic can be more powerful than any single card.
- Sparrow's Gloves: At the start of each turn, gain 2 Combo. This gives you a head start every single turn.
- Executioner's Hood: Attacks deal +3 damage to Marked enemies. This turns every small hit from Thousand Cuts into a real threat.
- Tome of Swiftness: The first time you play 3 cards in a turn, draw 1 card. Essential for continuing your combo chain.
During this phase, you are looking for your key damage cards and their upgrades. A campfire should almost always be used to upgrade Unseen Threat or Thousand Cuts before anything else.
Late Game (Floors 11+): Finding Rare Finishers and Perfecting the Engine
By now, your deck should have a clear identity. You're either a Combo/Thousand Cuts machine or a Mark/Blade Dance assassin. Now you're looking for the rare cards that push your build over the top.
- Flow State (3-cost Power): At the start of your turn, draw 1 extra card and gain 1 energy. This is a permanent buff that fuels your combo turns.
- Precision Edge (0-cost Skill): Your next attack deals double damage. Exhaust. The ultimate setup for a massive Blade Dance.
Don't be afraid to skip card rewards. At this stage, adding a card that doesn't fit your engine is worse than adding nothing at all. Consistency is king.
Adapting Your Strategy for Major Bosses
Your engine is powerful, but it's not invincible. The three act-end bosses require slight adjustments to your game plan.
The Stone Sentinel: Overcoming High Armor
The Stone Sentinel will constantly gain large amounts of Block and has a passive that reduces all incoming damage by 1. This second part is devastating for Thousand Cuts, as it can reduce many of the hits to zero.
The strategy: This fight is all about Mark. The Sentinel's damage reduction is applied before the Mark multiplier. You must land an early Unseen Threat and then use a single, massive hit from a card like Blade Dance to punch through its armor. Do not rely on multi-hit attacks here; focus on one big knockout blow.

The Crimson Weaver: Managing Minions
This boss constantly summons low-health Spiderlings that can overwhelm you. She is a direct test of your deck's area-of-effect capabilities.
The strategy: This is where Thousand Cuts shines. Ignore the Weaver at first. Build up a moderate Combo count (15-20 is often enough) and use Thousand Cuts to clear the board of Spiderlings. Once the board is clear, you can focus your high-damage attacks on the boss. Trying to race her down while ignoring the adds is a recipe for disaster.
The Void Lich: Playing Around Curses
The Void Lich attacks your deck directly, adding debilitating Curse cards like Burn and Void to your draw and discard piles. These clog your hand and prevent you from executing your combo.
The strategy: Speed is everything. You must defeat the Lich in the first 1-2 deck cycles, before the Curses overwhelm you. This is the ultimate test of your engine's efficiency. An opening hand with Unseen Threat and the ability to cycle into Blade Dance is your ideal scenario. Take calculated risks and prioritize damage output over perfect defense. You cannot outlast the Void Lich; you must blitz it down.
Frequently Asked Questions
How do you increase damage in Decks of Dexterity? The primary ways are by increasing your Combo counter before playing a Finisher card, applying stacks of the Mark debuff to enemies to multiply damage taken, and finding relics like the Executioner's Hood that provide passive damage bonuses.
What is the best combo for the Void Lich? The fastest and most reliable combo is to land an upgraded Unseen Threat on turn one to apply 10 stacks of Mark, then use cheap draw cards like Flicker to build a Combo count of 20+ and hit it with a Blade Dance finisher. The goal is to end the fight before it can fill your deck with Curses.
Is a Mark build viable in Decks of Dexterity? Yes, it's one of the strongest archetypes in the game. A Mark build excels at single-target boss killing, using cards like Unseen Threat to set up devastating finishers like Blade Dance. It can struggle with multi-enemy fights unless paired with cards like Thousand Cuts.
How does the Combo mechanic work? Combo is a counter that increases by 1 for every card you play during your turn. It starts at 0 each turn and resets when you press the "End Turn" button. Cards with the "Finisher" keyword use your current Combo count to calculate their damage or effect.
The Final Cut
Success in Decks of Dexterity isn't about finding one single "best card." It's about recognizing the powerful synergies between cheap, efficient engine pieces. Focus on building a deck that can play many cards in one turn, and you'll find that the best damage cards in Decks of Dexterity are the ones that reward you for it. Prioritize consistency, hunt for the right relics, and always be thinking about how each card contributes to your final, boss-killing combo.
