Duel of Champions Archive · How to Play
From building a first deck around a faction to reading the board on turn one, this covers the full shape of how a match actually worked.
Learning how to play Duel of Champions comes down to three linked systems: a deck built around one of six factions, a turn structure that alternates resource generation with unit deployment, and a lane-based board where those units actually fight. Duel of Champions deck building is where every match starts, since the cards in a player's deck determined what kind of game they'd be able to play before a single turn passed. This guide walks through all three systems in order, then covers the specific Duel of Champions rules that governed combat, resources, and the win condition.
None of this requires the original servers to understand. The rules of the game are fixed knowledge, independent of whether a client can currently connect to anything, and they hold up as a description of how a match played regardless of server status. For the current server situation instead, the status page covers that separately, and it's a genuinely separate question from the one this guide answers.
Every deck in Duel of Champions was built around one of the game's six factions: Academy, Haven, Inferno, Necropolis, Sanctuary, or Stronghold. That faction choice set the tone for the whole deck, since each faction's card pool leaned into a different strategic identity: Academy toward spellcraft and preparation, Haven toward steady defense, Inferno toward early aggression, Necropolis toward long-game attrition, Sanctuary toward evasive tempo, and Stronghold toward raw force. A deck wasn't required to use cards from only one faction, but the core identity of most decks came from committing to one faction's strengths and building the rest of the deck to support them.
Within a chosen faction, deck building meant balancing three broad card types: units, spells, and the champion's own abilities. Units were the backbone of board presence: the creatures a player actually deployed to fight. Spells provided direct effects, removal, or support that units alone couldn't. The champion itself sat outside the normal deck and brought its own ability kit and health pool into the match, functioning as both the player's avatar and their primary win-or-lose resource. Duel of Champions deck building meant deciding how much of a deck's identity would come from aggressive units versus spell support versus leaning on what the champion itself could do turn to turn.
A first-time deck builder's most important decision, in practice, was faction choice, not any individual card. Reading through each faction's page (Academy, Haven, Inferno, Necropolis, Sanctuary, and Stronghold) before committing to a deck is a faster way to find a fit than trying to learn all six strategic identities from a single overview.
A turn in Duel of Champions followed a consistent rhythm: generate resources, then spend them. Players alternated turns instead of acting simultaneously, and each turn gave a player access to resources they could spend on deploying units, casting spells, or using abilities available to them that turn. This resource-then-spend rhythm is one of the most standard rules shared across the whole trading-card-game genre, and Duel of Champions followed that same basic pattern instead of inventing an unusual alternative.
What a player could do within their own turn came down to reading the board, deciding which units to deploy or attack with, and choosing whether to hold spells in reserve or commit them immediately. Because turns alternated strictly, tempo mattered: a player who used a turn inefficiently gave their opponent a genuine, concrete advantage on the very next turn, not just a vague sense of falling behind. That back-and-forth rhythm is also why faction choice interacted so directly with the turn structure: an aggressive Inferno deck wanted to spend its early turns pressuring the opponent, while a defensive Haven deck was often content to use its early turns setting up instead of attacking outright.
Learning the rules of a turn is really learning to read tempo: whose turn currently favors aggression, and whose favors patience. That reading changed constantly as the match progressed and as each side's board state shifted.
Combat in Duel of Champions took place on a lane-based board rather than a single open battlefield. Units were deployed into specific lanes, and where a unit sat relative to the opposing side's units determined what it could attack and what could attack it back. This lane structure is what separated Duel of Champions from board-less card games. Position mattered as much as raw unit stats, and a strong card deployed into the wrong lane could be far less effective than a weaker card placed correctly.
Reading the board meant tracking two things at once: which lanes were contested and which were open, and which of the opponent's units posed the most immediate threat if left unanswered. Because the board was lane-based, not free-form, players could plan several turns ahead by anticipating which lanes an opponent was likely to reinforce, instead of only reacting to whatever appeared in front of them turn to turn.
This is also where faction identity showed up most visibly in play. A Stronghold deck tended to want direct, lane-clogging confrontations that let its raw power dominate a single point of contact. A Sanctuary deck, by contrast, tended to prize the flexibility to reposition or avoid a bad lane matchup altogether, leaning on evasive units rather than committing to a straight fight. Reading the board correctly meant recognizing which of those two postures (direct confrontation or evasive repositioning) a given matchup actually rewarded.
Resource generation and combat resolution were the two mechanical pillars underneath everything already covered above. Resources accrued each turn and were what actually paid for deploying units, casting spells, and activating abilities. Without spending on the turn structure described earlier, a hand full of strong cards was worth nothing. Combat itself resolved along the lines set by the lane-based board: a unit's position determined what it threatened and what threatened it back, and the outcome of an exchange came down to comparing the units actually facing off in a given lane, not comparing whole decks in the abstract.
Two Duel of Champions rules mattered more than most once a match reached its middle turns. First, tempo compounded: falling behind on a single turn's resource spending tended to compound into falling behind on board position too, since an opponent with a stronger board could then dictate which lanes stayed contested. Second, a champion's own abilities were a resource in their own right, not just a passive health total sitting in the background; knowing when to activate a champion ability versus holding it in reserve was as much a rules-literacy question as knowing what any individual card did.
The win condition in Duel of Champions was simple to state even though reaching it could take a long match: reduce the opponent's champion to zero health before they did the same to your own. Every unit deployed, spell cast, and lane contested ultimately mattered only insofar as it moved a player closer to that single outcome. There was no secondary win condition and no points-based alternative. Matches ended when one champion's health hit zero, full stop.
That single, clear win condition is part of why faction identity mapped so cleanly onto play style. An aggressive faction like Inferno aimed to reach that zero-health outcome as quickly as possible, before a slower deck could stabilize. A patient faction like Necropolis aimed to survive long enough that its attrition-based advantages eventually made the outcome inevitable rather than fast. Both were valid paths to the exact same win condition; the rules didn't reward one approach over the other in principle, even if certain matchups favored certain factions in practice.
Understanding the rules this way (one win condition, reached through whichever combination of deck-building, turn management, and board control a faction's identity supported) is really the whole shape of how to play Duel of Champions. Everything else in the game was in service of that single outcome.
Put together as a single guide, the path to learning Duel of Champions runs in a fairly natural order: pick a faction that matches the play style that appeals most, build a deck around that faction's units, spells, and champion kit, then practice reading the rhythm of alternating turns and the geometry of the lane-based board. None of those pieces work in isolation: a strong deck built around the wrong turn-by-turn plan underperforms, just as a sound tactical plan without a deck built to support it runs out of resources before it can close out a match.
For anyone starting from zero, the most efficient order is usually faction first. Committing to Haven, for instance, immediately narrows the deck-building question down to which defensive tools to prioritize, and narrows the turn-by-turn plan down to patient, board-stabilizing play rather than trying to out-race an Inferno deck at its own game. The full factions comparison is the fastest way to make that first decision, and each individual faction page goes deeper into how that faction specifically played once a deck starts coming together.
Playing Duel of Champions meant building a deck around one of six factions, then alternating turns with an opponent (generating resources, deploying units onto a lane-based board, and casting spells) until one player reduced the other's champion to zero health. That single win condition sat behind every deck-building and in-match decision.
Haven's steady, defense-first identity tends to be the easiest starting point, since it punishes early mistakes less severely than a faction like Inferno that relies on fast aggression. That said, the right faction really comes down to which play style appeals more, since each of the six has a distinct, viable identity.
The core rules boiled down to alternating turns, resource generation feeding unit and spell deployment, and combat resolved on a lane-based board. The match ended the moment one player's champion reached zero health, which was the single win condition governing every other rule.
Deck building started with choosing one of the six factions, then filling out a deck with that faction's units, spells, and support for its champion's abilities. Duel of Champions deck building rewarded committing to a faction's core identity instead of spreading a deck thin across unrelated strategies.
Units didn't fight on one open battlefield. They were deployed into specific lanes, and which lane a unit occupied determined what it could attack and what could attack it. Reading the board meant tracking contested versus open lanes and planning deployments around that lane structure, not around raw stats alone.
A match was won by reducing the opposing champion's health to zero. There was no alternate or points-based win condition; every deck-building and turn-by-turn decision ultimately served that single outcome.
Yes. The rules of how to play Duel of Champions (deck building, turn structure, lane combat, and the win condition) are fixed knowledge about the game itself and don't depend on whether the original servers are currently running. Server status is covered separately on the status page.
Six: Academy, Haven, Inferno, Necropolis, Sanctuary, and Stronghold. Each had a distinct strategic identity, and deck building generally started by committing to one of the six instead of mixing evenly across all of them.
Units were the deployable creatures that occupied lanes and did most of the fighting. Spells were direct one-time effects (removal, support, or disruption) separate from unit deployment. The champion sat outside the normal deck, bringing its own ability kit and health total into the match as both a resource and the target of the win condition.
Broadly, yes. Alternating turns and resource-based deployment are standard across the trading-card-game genre. What set Duel of Champions apart within that genre was its lane-based board, which made unit position as important as unit strength instead of resolving combat in a single open battlefield.
Starting with the six factions is the most efficient path, since faction choice shapes every later deck-building and turn-by-turn decision. The factions overview compares all six side by side before this guide's rules sections go deeper into turns, the board, and the win condition.
