Players play matches to earn credits, which are then used to mint new cards via card packs. A card pack contains 15 randomly selected cards from the current card set in print. Once a card set goes out of print, new card packs for that set can no longer be created, creating a cap on the supply of those cards.

A match consists of players taking turns, building their deck by buying cards from their sideboard, casting spells and attempting to beat their opponent. This is usually done by reducing the opponents' life total to zero, or below.

When a winner is determined, the match ends, and new credits are distributed to the players. The winner receives the majority of the credit. However, the losing player will also gain some credits, provided they did not concede or disconnect.

Once a player has minted some cards with credits, they may trade them on the market and earn Bitcoin. In summary, Legends of Uzarn and its player economy are set up in such a way to maximize value for the players, which provides the possibility to make a decent profit from playing, both in the short and long term.

Starting a Game

To start a match, you must first join the match-making queue. A popup will appear, prompting you to choose what deck you would like to play with. New players will automatically have four valid decks generated for them using 60 starter cards.

The chosen deck must be valid for the chosen format. Currently, the only format is Standard. If the deck is not valid, a warning will appear, specifying why the deck is invalid.

For more information on building your own deck, visit Deck Builder.

Once you have joined the match making queue, the game will wait for someone of a suitable match to do the same, pair you with them, then notify you that the game is about to begin.

Playing a Game

Once the game loads, a random player is chosen as the first player. Each player then draws their initial hand from their deck.

The first player draws 3 cards, while every other player draws 5. The Upkeep phase of the first player's turn now begins.

The current turn player then moves through the turn phases, buying cards from their sideboard with mana and casting spells to create a powerful game board, that will lead to victory.

The current turn player is denoted by their name in yellow text. Players who it is not currently their turn, have their name in white.

When a player draws from their Deck, it is called a Draw Action. Many cards can be drawn in a single Draw Action, for example, Draw 3 cards is a single Draw Action.

If a player's Deck does not have enough cards to satisfy a draw action, all cards in their Discard are shuffled into their Deck, and the draw action continues.

If a player draws 4 cards and their Deck has 1 card and their Discard has 5 cards, the 1 card from their Deck is drawn, the 5 cards in their Discard are shuffled into their deck, then 3 more cards are drawn. This all happens in a single action.

If a player draws 4 cards, their Deck has 1 card and there is no cards in their Discard, then only 1 card will be Drawn.

If a player commences a Draw Action while there is no cards in their Deck and no cards in their Discard, they will lose the game. If there is at least 1 card in their Deck or Discard however, they will not lose the game, even if the draw amount is greater than the available number of cards.

In order to create a powerful deck to win, you have to build your deck while the game progresses. This is done by purchasing more powerful cards from your sideboard with mana. The sideboard is a secondary collection of cards which start outside the game.

When you build your deck, you define what cards a present in your sideboard based on what cards you own in your collection.

In order purchase a card, it must be your turn, it must be either the First Main or Second Main phase, you must have priority, and there must not be any card or action currently on the game stack.

To purchase a card, click on the Buy button, on the lower left hand side of the screen, below the game stack.

Open Sideboard
Click the Buy button to open your sideboard anytime

Your sideboard collection will appear and you may click on any number of cards. The buy cost for each card is printed on the top right of the card. Once you have decided what cards to buy, click the Buy button down the bottom. The interface will then prompt you to pay the total mana cost of all the selected cards. If you cannot pay the mana cost, the purchase is cancelled and no action is taken.

Mana is generated using Treasures in your hand, and Permanent Treasures, which sit on the Battlefield. Treasures in your hand are "spent", meaning they are placed in your Discard once used, while Permanent Treasures persist on the battlefield and can be used each turn.

To cast a card, it must first be in your Hand, you must have priority, and the casting rules for the respective Card Type must be satisfied. Once this is true, you may cast it for free by clicking on it.

Some cards have additional costs that you must pay in order to cast it, such as pay X mana or trash a card. Once a spell is casted, it goes onto the Stack.

Each player may then respond to the spell by casting an instant or activating an ability. If they choose not to, priority is passed and the card resolves. Once resolved, it is placed onto the Battlefield.

A common way of winning is by playing Creatures and attacking with them. Normally, Creatures cannot attack or activate abilities on the turn they enter play. This effect is called summoning sickness.

A Creature not affected by summoning sickness
No longer affected by summoning sickness.

Creatures can attack during the attack phase and deal damage to opponents or their Creatures.

Players progress through turns until only one player is left alive, and they are declared the winner. If all the players lose at the same time, the game is declared a draw, and Credits are distributed evenly.

Card Types

  • Treasure - Treasures are spent from your Hand and add mana to your pool A spent Treasure is immediately put into your Discard.
  • Creature - Creatures are permanents cast during Main phases and can be used to attack opponents and their Creatures. Most Creatures have summoning sickness meaning they cannot attack, or activate abilities until their controller's next turn. Creatures with Haste are not effected by summoning sickness. When a Creature is affected by summoning sickness, it has the chains visual effect placed over the card.
  • Relic - A permanent card that often has activated abilities. These activated abilities may perform any type of action.
  • Aspect - A permanent card that sometimes has activated abilities but often has effects which alter the rules of the game. Aspects can buff your cards and abilities or hinder your opponent's.
  • Aura - An Aspect that can enchant a permanent or player. If the enchanted permanent leaves the battlefield, the attached Aura is discarded.
  • Sorcery - A powerful spell that can only be cast during your Main phases while the game stack is empty. Casted sorceries go onto the Battlefield and are then moved to your Discard during the Cleanup phase.
  • Instant - Instants function the same as Sorceries, except they can be cast at any time you have priority, even during an opponent's turn.
  • Permanent Treasure - Permanent Treasures cannot be spent from the Hand and must be placed onto the Battlefield before being used. Typically, only one Permanent Treasure can be played on each of your turns.
  • Curse - A Curse is a negative card that is placed in your opponent's Discard. This dilutes their deck and wastes draws. Additionally, some Curses may perform an ability when that player draws them. Once the Curse is drawn, it remains in that players Hand until they discard it, or Trash it with an ability.
  • Bomb - Bombs are similar to Curses in that they are placed into opponent's Discards, however when a Bomb is drawn, it performs the ability printed on the card, then it is trashed.

Card Rarity

Cards have 1 of 5 rarity types. Cards with higher rarity are harder to find in Card Packs and are significantly more powerful. Rarity is indicated by the color of the set icon on the bottom of the card.

  • Basic Treasure - Basic starting Treasure. Has a power level of 0 and is mostly used to fill starter decks. The set icon is white.
  • Common - Common rarity card. Can be used in starting decks provided their power level does not exceed the format rules. The set icon is white.
  • Uncommon - More powerful cards that cannot be present in starting decks. Usually the first cards you will purchase from your sideboard. The set icon is blue.
  • Rare - Powerful and expensive cards. Only 1 rare is present in each card pack. These are valuable cards which will win you the game. The set icon is gold.
  • Mythic - Very powerful and valuable cards. A Card Pack only has a 20% chance of containing a Mythic card. The set icon is red.

Legendary cards are special cards that are extremely powerful but also play a significant part in the lore. They are marked "Legendary" in the card type box. They are often characters who recur throughout the sets or play a significant role in that set's theme. A deck may only contain a single copy of each Legendary card, even if it is a reprint from a different set.

Card Attributes

  • Stealth - This Creature cannot be attacked during Declare Attackers phase.

Warp Counters

Warp counters are counters that are added to players. Many Purple cards require Warp counters to be useful so getting them is central to Purple's strategy. The downside to acquiring Warp counters is whenever you take damage from any source, that damage is increased by the number of Warp counters you have. Only abilities that state damage in their text have this effect. Loss of life is not effected by Warp counters.
