Card Anatomy & Speeds

• Creature: Units deployed onto the board. Defined by stats: Mana Cost, ATK, HP, SPD (movement), and AP (actions per turn).
• Spell: Magical effects. Resolves via the Stack and requires Mana.
• Skill: Tactical abilities. Resolves via the Stack. Costs alternate resources (never Mana).
• Equipment: Upgrades attached to a unit. Persists until the unit is destroyed.

Every Spell requires a source: a friendly miniature on the battlefield from which the Spell originates. All ranges, zones, and directional references on a Spell card are measured from the source model.

• Default source: The Hero is always a valid Spell source.
• Caster keyword: A unit possessing Caster may serve as the source for Spells played by its controller, in place of the Hero. The controller chooses which eligible source to use at the moment the Spell is played.
• If multiple Casters are in play, the controller freely chooses the source each time.
• A Caster that is Destroyed or Exhausted cannot serve as a source.
• Global Spells (no physical target or range — e.g., draw effects, personal mana gain): The source is declared but does not affect resolution.

Every Skill requires a source: a friendly miniature on the battlefield from which the Skill originates.

• Default source: The Hero is always a valid Skill source.
• Skilled keyword: A unit possessing Skilled may serve as the source for Skills played by its controller, in place of the Hero.
• A player cannot play a Skill unless they control at least one non-Exhausted Skilled or their Hero on the battlefield. This rule is global and is not repeated on individual Skill cards.
• A Skilled that is Destroyed or Exhausted cannot serve as a source.
• The Hero may be Exhausted like any other Skilled. If the Hero is Exhausted and no other non-Exhausted Skilled is in play, the player cannot play any Skill until the Exhaust resolves.

Every action and card belongs to one of two speed categories:

• Standard: Playable only during your own Main Phase, and only when the Stack is empty.
  • Default: Creatures, Equipments.
• Quick: Playable at any time you hold Priority (including during your opponent's turn, or in response to an action on the Stack).
  • Default: Skills, designated Spells.
