AbilityFactory
[[TOC]]
NOTE: These factories are refactored from time to time (often to adapt to new sets), so while some entries could be slightly outdated, the base information should still be correct.
AbilityFactory parses differently from the Keyword parser. Your Ability line will look more like this:
A:{AB/SP/DB/ST}$ <AFSubclass> | {Necessary$ Parameters}| {Separated$ By} | {Pipes$ Here}
In most cases, each AF subclass implements both the Spell and Ability. Much of the code is shared, so creating the data object will look very similar.
- AB is for Activated Abilities.
- SP is for Spell.
- DB is for Drawback and for many abilities that are subsidiary to other things, like replacements. They are only used to chain AFs together, and will never be the root AF.
- ST is for Static, this gets used in case the API should resolve without using the stack (e.g. special actions)
Cost$ <AbilityCost> is the appropriate way to set the Cost of the Ability. Currently for spells, any additional costs including the original Mana cost need to appear in the Cost parameter in the AbilityFactory. For each card that uses it, the order in which the cost is paid will always be the same.
Secondary abilities such as the DB executed by triggers or replacements don't need costs. (This is one reason to use DB over AB in these cases.)
Read more about it in Costs
There are two different ways to Target. One or the other will need to be used for Spells/Abilities that target. If your effect does not target, but instead defines what will be affected by the Spell/Ability, use the Defined Parameter.
Read more about it in Affected / Targets
Restriction restricts when spells/abilities can be activated or resolved. Common examples are Putrid Leech's only activate this once per turn or different cards that can activate from Zones like the Hand or the Graveyard.
SpellDescription is how the text of the ability will display on the card and in the option dialog for cards with multiple abilities.
The SpellDescription for secondary abilities (both AB and DB) is now displayed when (and if) the ability prompts for user input in the prompt pane so it is useful to put some nice text there.
(Optional) StackDescription is the description the ability will have on the stack. This is automatically generated by the effect, but may be overridden using this parameter. This is sometimes needed with complex effects, when the generated text can't handle some details. Properties of the spell can be accessed like this: {c:Targeted}. You can reuse the spell text by just putting SpellDescription or None to leave it empty.

AB$ Attach | Cost$ R R | ValidTgts$ Creature | AILogic$ Pump
Parameters:
- Object (optional) - This is the Object that will be Attached (generally the Source Card for Auras)

Attach separates the actually granting of abilities from the attaching to permanents to streamline how things work.
Soulbonding two creatures
Sometimes, an ability might do certain things when a specific condition is true, and other things if not. This can be implemented by using Branch.
The branch evaluates the SVar specified by the property BranchConditionSVar, using the comparison defined with BranchConditionSVarCompare (such as GTY, LT1, etc). Depending on whether the condition evaluated to true or false, the subability defined by TrueSubAbility or FalseSubAbility is executed.
The example below is for "Composer of Spring", which allows either a "land" or a "land or creature" to be put on the battlefield, depending on the number of enchantments in play under your control.
SVar:TrigBranch:DB$ Branch | BranchConditionSVar$ X | BranchConditionSVarCompare$ GE6 | TrueSubAbility$ PutLandCreature | FalseSubAbility$ PutLand
SVar:PutLand:DB$ ChangeZone | Origin$ Hand | Destination$ Battlefield | Tapped$ True | ChangeType$ Land.YouOwn

Changing a cards State. This is mostly for Flip Cards or the Transform mechanic.
ChangeZone is a united front of any card that changes zone. This does not include: drawing, discarding, destroying, or milling, as these represent specific words on which triggers and replacements can react. There are two primary forms, but the distinction is handled mostly in the codebase. The only thing that is required is to set appropriate parameters.
Origin and Destination are both required.
Origin is where the card is coming from.
Destination is where the card is going to. If Destination is Library, a LibraryPosition is recommended, but not required. Default value of the LibraryPosition is 0. 0 represents the top of the library, -1 represents the bottom.
There are two primary versions of ChangeZone.
The first is hidden, generally used for Origin zones that are not known information, like the Library or the Hand. The choice of "What card is changing zones?" happens during resolution.
A:SP$ ChangeZone | Cost$ W | Origin$ Library | Destination$ Library | LibraryPosition$ 0 | ChangeType$ Artifact,Enchantment | ChangeNum$ 1 | SpellDescription$ Search your library for an artifact or enchantment card and reveal that card. Shuffle your library, then put the card on top of it.
A:AB$ ChangeZone | Cost$ T | Origin$ Hand | Destination$ Battlefield | ChangeType$ Land | ChangeNum$ 1 | Optional$ True | SpellDescription$ You may put a land card from your hand onto the battlefield.
For Hidden, things like ChangeType and ChangeNum are used to restrict what can ChangeZone, and how many do. There are two parameters special to Hidden Origin:
"Chooser" defines which player has to decide which card changes zone (example You, Opponent).
"Mandatory" most of these abilities are not mandatory, but some are.
The second is known, generally used for Origin zones that are known information, like the Battlefield or the Graveyard. The choice of "What card is changing zones?" happens on activation, generally by targeting.
A:AB$ ChangeZone | Cost$ 1 U T | TgtPrompt$ Choose target artifact card in your graveyard | ValidTgts$ Artifact.YouCtrl | Origin$ Graveyard | Destination$ Library | SpellDescription$ Put target artifact card from your graveyard on top of your library.
A:SP$ ChangeZone | Cost$ U U | ValidTgts$ Permanent | TgtPrompt$ Select target permanent | Origin$ Battlefield | Destination$ Hand | SpellDescription$ Return target permanent to its owner's hand.
For Known, since it just uses Target, normal target parameters are used in this Scenario.
This is a helper AF, for chained effects that create multiple permanents which should enter the battlefield at the same time.
To use it, you need to set the param "ChangeZoneTable" on the first effect and then call this at the end.
This is supported by the following effects:
- Amass
- CopyPermanent
- RepeatEach (NOTE: if you wrap the creation, you don't need to call this AF on its own)
- Token
This allows cards that have a mode to be chosen to occur after a trigger.
Parameters
- CharmNum - Number of Modes to Choose
- Choices - A Comma delimited list of SVars containing the Modes
This can be used when you are asked to choose a card type or creature type.
- Type - Required - Can be Card or Creature
- InvalidTypes - Optional - Use to specify any type that cannot be chosen (ex: "Choose any creature type except Wall")
The Defined is for target players.
NOTE_: Make sure that when this is used with a SubAbility that the DB$AF_Whatever will support Card.ChosenType. This will need testing on a case by case basis.
This AF handles clashing. It takes two special parameters: WinSubAbility and OtherwiseSubAbility. They are both optional and work the same way, namely that it contains the name of an SVar that in turn contains a drawback to be executed. The example below is for Release the Ants.
A:SP$ DealDamage | Cost$ 1 R | Tgt$ TgtCP | NumDmg$ 1 | SubAbility$ DBClash | SpellDescription$ Release the Ants deals 1 damage to target creature or player. Clash with an opponent. If you win, return CARDNAME to its owner's hand.
SVar:DBClash:DB$ Clash | WinSubAbility$ DBReturn
SVar:DBReturn:DB$ ChangeZone | Defined$ Self | Origin$ Stack | Destination$ Hand
A non-functional, maintenance AF used for Cleaning up certain Variables before a Spell finishes Resolving.
Parameters
- ClearRemembered$ (optional) Set to True to clear this card's remembered list. Generally useful for Cards that Remember a card, do something to it, then need to forget it once it's done.

Effect is an oddball of the AF family. Where usually AFs have similarities to each other to help with AI use, Effect doesn't fall under that jurisdiction. In general, an effect is some type of SA that lasts longer than its resolution.
A good example is High Tide. For the rest of the turn, High Tide makes all Islands produce an extra mana. It doesn't matter if the Island was in play, if it turned into an Island after High Tide was cast, any of that.
A:SP$ Effect | Cost$ U | Name$ High Tide Effect | Triggers$ IslandTrigger | SVars$ TrigMana | SpellDescription$ Until end of turn, whenever a player taps an Island for mana, that player adds U to his or her mana pool (in addition to the mana the land produces).
SVar:IslandTrigger:Mode$ TapsForMana | ValidCard$ Island | Execute$ TrigMana | TriggerDescription$ Whenever a player taps an Island for mana, that player adds U to his or her mana pool (in addition to the mana the land produces).
SVar:TrigMana:AB$Mana | Cost$ 0 | Produced$ U | Amount$ 1
Effect is most similar to Token as it creates a pseudo-permanent, except Effect creates in the command zone rather than the battlefield. It stays active there for a set Duration.
Parameters
- Abilities,Triggers,SVars are comma separated lists which contain SVars that point to the appropriate type that the Effect will gain.
- Duration is how long the Effect lasts. Right now, most effects will last Until End of Turn. In the future, they may have other conditions.
Duration$ Permanent for effects that have no specific Duration.
- Stackable$ False - Most Effects are assumed to be Stackable. By setting the Stackable Flag to False, the AI will know having a second one in play is useless, so will save it's Resource for something else.
- Image - a file_name_without_extension (image needs to reside in the tokens directory)
Used in the script of Karn Liberated
Fog is an ability based on the original Fog spell. "Prevent all combat damage that would be dealt this turn." While this could be done with an effect, the specialized nature of the AI gives it it's own AF.

Look at a player's hand.
Target or Defined is required.

A:AB$ Scry | Cost$ 1 T | ScryNum$ 2
A:AB$ Reveal | Cost$ 2 U T | Defined$ You | RevealValid$ Card.Blue | AnyNumber$ True | RememberRevealed$ True

This AF is very similar to things that Dig can do, but handle a much simpler form, with less complex coding underneath. Similar to how RearrangeTopOfLibrary could be handled with Dig.
Primarily used with cards that allow you to Peek at the top card of your library, and allow you to reveal it if it's of a certain type. The Kinship cards fit this bill perfectly, so they are used to simplify the complex popups that would be required if using multiple Dig SubAbilities.
RevealOptional - Whether or not the Reveal is optional.
RememberRevealed - Whether to remember the revealed cards (after filtering by Valid)
RememberPeeked - Whether to remember the peeked cards (only if they are not revealed!)
RevealValid - defaults to Card, but allows you to set a specific ValidType if you can only have certain things
PeekAmount - defaults to 1, but allows you to peek at multiple cards if possible
Usually you choose a player and that player has to sacrifice something
A:SP$ Sacrifice | Cost$ 1 B | ValidTgts$ Player | SacValid$ Creature | SacMessage$ Creature | Amount$ 2 | SpellDescription$ Target player sacrifices a creature.
Destroy$ True - An optional parameter for destroying permanents target player chooses (eg: Burning of Xinye, or Imperial Edict).
A:SP$ Sacrifice | Cost$ 1 B | ValidTgts$ Opponent | SacValid$ Creature | SacMessage$ Creature | Destroy$ True | SpellDescription$ Target opponent chooses a creature he or she controls. Destroy it.
Token simply lets you create tokens of any type.
A:SP$ Token | Cost$ 3 W U | TokenImage$ W 1 1 Bird Flying | TokenAmount$ X | TokenName$ Bird | TokenTypes$ Creature,Bird | TokenOwner$ You | TokenColors$ Blue | TokenPower$ 1 | TokenToughness$ 1 | TokenKeywords$ Flying
This ability factory does not take a target. All the parameters are mandatory except for TokenKeywords. If you provide a non-integer for TokenAmount, TokenPower or TokenToughness the AF will attempt to look for an SVar of that name and interpret it's contents as a Count$ line. Worth noting is that TokenTypes and TokenColors are simple commaseparated lists while TokenKeywords is a list where the items are separated by "<>". If TokenImage is not provided, the factory will attempt to construct a filename on it's own. TokenOwner can use Defined-like parameters, such as "You" "Opponent" or the new Triggered-Variables.
You can also use the parameters TokenAbilities$, TokenTriggers$ and TokenSVars$ to give the created tokens any number of either. For example, here's how Growth Spasm creates an Eldrazi Spawn token complete with ability.
SVar:DBToken:DB$Token | TokenAmount$ 1 | TokenName$ Eldrazi Spawn | TokenTypes$ Creature,Eldrazi,Spawn | TokenOwner$ You | TokenColors$ Colorless | TokenPower$ 0 | TokenToughness$ 1 | TokenAbilities$ ABMana SVar:ABMana:AB$Mana | Cost$ Sac<1/CARDNAME> | Produced$ 1 | Amount$ 1 | SpellDescription$ Add 1 to your mana pool.
As another example, here's Mitotic Slimes' use of TokenTriggers$:
T:Mode$ ChangesZone | Origin$ Battlefield | Destination$ Graveyard | ValidCard$ Card.Self | Execute$ TrigTokenSenior | TriggerDescription$ When CARDNAME is put into a graveyard from the battlefield, put two 2/2 green Ooze creature tokens onto the battlefield.

SVar:TriggerJunior:Mode$ ChangesZone | Origin$ Battlefield | Destination$ Graveyard | ValidCard$ Card.Self | Execute$ TrigTokenJunior | TriggerDescription$ When this creature is put into a graveyard, put two 1/1 green Ooze creature tokens onto the battlefield.
