The card duel mode of the game attempts to simulate the experience of playing with actual Magic: The Gathering cards. The player is shown a tableaux that is divided into two halves - the lower half for the player's cards, and the upper half for the opponent's cards. Both players draw randomly from their own available cards (their personal "deck"), then proceed to play a standard game of Magic: The Gathering, based as closely as possible on Magic: The Gathering official rules. The match progresses in phases and turns, corresponding with the M:TG rule-set, with the program automatically skipping over certain phases when no action is possible and/or required. The player can set break-points to allow him or her to execute "fast-acting" spells or card abilities in case the program is not smart enough to automatically spot such possibilities. Each player's life-counter is displayed on their side of the playing field and will either rise or drop according to the progression of the game. The player can also rearrange his or her played cards to allow better visibility when the playing field becomes crowded, often during prolonged matches. When the card duel is initiated as part of the Single-Player Campaign, special rules may apply. Often this includes a higher (or lower) life counter for one or both players, a card that appears at the start of the match for one or both players, or a global effect that influences both players (either beneficial or detrimental, often depending on the composition of either player's deck).
Single-player campaign mode
The single-player campaign is played mainly on an isometric representation of the game world, consisting of a randomly generated landscape dotted with terrain features and places of interest. The player initially selects a difficulty level (determines starting gold, cards, amulets and the life totals of "boss" enemies) and a preferred magical "color", and subsequently is given a predetermined deck, according to difficulty level and color chosen. The character is then transported to the world map, initiating the game. Travel across the world map is in real-time. The player moves the character across the landscape using simple mouse clicks, evading or intercepting enemies who themselves are predominantly interested in intercepting the player-character. Upon a successful interception, the game transitions into "duel" mode, wherein either the player competes against the encountered enemy using the Magic: The Gathering card game system, or pays the enemy an amount of gold to not duel. When dueling an enemy, a card or set of cards is often wagered, with particularly powerful enemies sometimes offering additional rewards beyond the waged cards. Some enemies have unique abilities that allow them to gain a specific advantage for the duration of the battle, while some enemies can summon up a surprise substitution to play in their stead (e.g., a more powerful enemy). The landscape is composed of patches of different types of terrain, corresponding with the five colors of the game world. Different terrain might offer benefits or hindrance to movement, including roads through all terrain types which allow rapid movement. Terrain also dictates the boundaries across which enemies may travel, as they have to adhere to terrain matching their own color(s). More importantly, each type of terrain offers a chance for special encounters to appear, often unique to one terrain type or another. Such encounters yield anything from combat to instant rewards, and often include riddles that require some knowledge of the various game cards.
The world map contains a large number of cities which can be visited, and these form the backbone for the game's underlying role-playing mechanics. Each city offers some cards for sale of a color matching the terrain around the city; the purchase of food (required to prevent slow-downs on the world map due to hunger); and often quests that usually involve reaching another city, acquiring a specific card, or defeating an enemy in the nearby area. These quests often has a reward at the end wherein the play will receive cards, hints to castle secrets or Mana links. Obtaining Mana links raises the players life points. These Mana link can also be removed if the city in which it was obtained is overrun by a creature. Cities also buy cards from the player, allowing him or her to make money for the purchase of food, better cards and spend them in certain special areas (for example, to buy amulets from a Gem Bazaar). Some cities also offer special items that enhance player performance or allow the player to create special effects such as instant teleportation. Some of these effects, depend on the consumption of colored amulets that can be collected in various encounters, earned upon completion of quests, or purchased These gems can also be traded for rarer cards (generally those of the same color of the amulet) at various towns. The landscape also contains a handful of dungeons whose locations can be discerned through various means, particularly the completion of quests and the defeat of powerful enemies. Within a dungeon, life lost in each duel carries over to all others, and other special rules will apply which could hinder or enhance a player's abilities. For example, a particular card could be permanently in effect. The dungeon interface is made up of a randomly generated series of perpendicular tunnels, with enemies placed in various locations and intersections. The player has freedom of movement within the tunnels while enemies remain stationary, but the player cannot pass through a spot taken by an enemy without initiating combat with that enemy. The tunnels also contain bonuses that can be picked up which provide a random effect, often bestowing extra life points or a free creature at the start of the next duel. Dungeons are important because of the special, valuable and powerful cards contained within that can be found no where else, frequently offering one of the Power Nine.
The player's primary goal is to destroy the five evil mages who are vying to cast the Spell of Dominion, which will enable them to conquer Shandalar. To accomplish this, the player must seek out and destroy the castle of each and every mage. Castles are played similarly to dungeons, except they contain no special cards but instead house the mage him/herself. If the mage is defeated in a duel, the mage and the castle are permanently destroyed. Until defeated, each mage regularly sends minions to attack cities on the map, which requires the player to react promptly, traveling to this city within the allotted time and defeating the minion in a duel. If the player fails, either by losing to the minion or taking too long to respond, the enemy mage will establish a mana link at the city, leaving the now much more powerful minion to stand guard. If any one mage establishes enough mana links (3 or 5, depending on whether or not the player possesses a certain item) to cast the "Spell of Dominion", which will bring the plane of Shandalar under their control, the game is lost. After defeating all five mages, the player then has to confront a final enemy who plays with cards of all five colors. This enemy has vastly more life points than any other enemy in the game. The amount of damage the player manages to do to this final boss before the fight ends constitutes the player's final score for the campaign.
