Costs

Cost is a class that attempts to streamline costs throughout all cards. It requires that each cost is separated by a space. They can generally be found on every Ability, although certain Keyworded abilities do use Cost too.

CostDesc / PrecostDesc

UnlessCost

UnlessCost$ <AbilityCost> allows a player to pay costs to prevent the resolving of the ability.

Add UnlessPayer$ <Defined> for changing which players are included, defaults to "TargetedController".

If the script has the param UnlessSwitched$ <Defined>, then the player pays mana to resolve the ability (usually used to handle "any player may pay ..." ).

Types of Cost

The base syntax for more complex parts looks like this:
Part<Integer[/Type][/TypeDescription]>

Type is often a Valid property or CARDNAME / NICKNAME for Costs that do something to themselves (e.g. Sacrifice Self).

Description is the last parameter in the cost. This is to allow for complex Type definitions to have a better readable text.

Mana

For normal mana costs you can just write the shards directly like printed.

Examples:

• Cost$ B R - 1 black and 1 red mana
• Cost$ WG - Hybrid White/Green mana
• Cost$ S - Snow mana
• Cost$ Mana<2\Creature> - 2 generic mana produced by a source with type 'creature'. Note the backslash, it was chosen because hybrid costs already use slash
