This page will guide you through a game of Spellsource! We're going to assume that you already have a valid deck, but if you don't have that yet, take a look here to get started! If you're looking for more details about keywords or terminology, you can take a look here!
Spellsource is a 1v1 collectible card game where players will use minions, spells, and weapons in order to defeat their opponents! In the standard format, both players will have decks of 30 cards and begin with 30 HP. You lose if your HP drops to 0, so bring down your opponent's life before they do the same to you!
As stated earlier, both players will begin with 30 HP. Both players will
also begin with no Lun. We will return to this in the following section.
One player will randomly be selected to move first, and the other
second. In this section, Player 1 will move first and Player
2 will move second. Player 1 will begin with 3 cards in their hand
whereas Player 2 will begin with 4 cards in hand. Before they even move,
both players are allowed to select any number of the cards in their hand
to return to their respective decks. For each card they return, they
draw a card to replace it. This is what we calling a mulligan. After
both players have finished their mulligan, Player 2 will receive a
Lunstone. At this point, the game will begin!

Each player has multiple different zones to utilize.

Each player's turn will begin with their upkeep. During this, the player
will refresh all of their used Lun, gain a new Lun, and draw a card from
their deck. There may also be cards that trigger at the beginning of the
player's turn, which will do so at this time.
Now, the player may make their turn! Every card has a number in the top
right corner. That is its Lun cost. In order to play that card, you will
need to use that much of your Lun in reserve. In addition to playing
cards, a player can also attack with their minions or sometimes their
champion! Selecting the character that should attack and the desired
target will make the two targets fight. After fighting, both targets
will lose health equal to the other's attack. Any minion that drops to 0
health will be destroyed. Newly played minions will have "summoning
sickness" and can't attack until the owner's next turn.
In Spellsource, attacking and playing cards can occur in any order! A player can attack with one minion, play some cards, then attack with their other minions! With a great deal of flexibility, a player can make any number of potential move combinations to achieve victory.
When a player feels satisfied with their turn, they may end their turn, triggering any effects that may occur as a result and letting the opponent begin their turn. This process will repeat until a player's health falls to 0!
When a player tries to draw a card when there are no cards left in their deck, they will begin taking Fatigue damage. The first attempted draw will deal 1 damage, the second will deal 2, etc. This growth in damage means that once a player starts taking fatigue damage, they won't have much time before losing the game!
