The language of Triune
Five ways to
shape the battle.
Exact card text always controls. These are the roles each card type normally plays.
Avatars
Your combatants. Manifest them in Offense or Defense and use PWR or GRD to control battle.
Elite Avatars
Special champions that begin in the Elite Deck and enter play through printed Manifestation requirements.
Veins
Spell-like cards. Normal Veins are Speed 1; R-Effect Veins can answer legal actions at Speed 2.
Relics
Persistent cards that remain in an Action Zone to provide repeatable, triggered, or continuous value.
Mysts
Mysts are limited, powerful spells.
Reading your cards
How to Read Card Effects
Cost, Result, and Restrictor describe different parts of an effect. Not every effect has all three. Exact card text always controls.
Pay the Cost, then activate the effect. When it successfully resolves, receive the Result. Some cards also require a Restrictor: an extra payment made by accepting a limit on what you can do afterward.
- Cost
- Everything before the semicolon, including targeting. Complete the Cost before activation; it cannot be interrupted. You must still follow legal timing and make legal selections.
- Result
- What happens when the effect resolves.
- Restrictor
- An extra payment made by accepting a stated limit. Apply it after successful resolution, according to the card’s wording.
Read it in three parts
CostYou can target 1 card your opponent controls; Resultdestroy it, Restrictorand if you do, for the rest of this turn after this effect resolves, you cannot Manifest Avatars from the ED.
ED means Elite Deck. Selecting the target is the Cost; destroying it is the Result. Because this example says “and if you do,” its Restrictor applies only if that target is actually destroyed.
This limit starts after the effect resolves and lasts for the rest of this turn. Other Manifestation requirements and full-turn eligibility rules still apply.
Spot the effect’s speed
Normal-speed activated actions
Normal-speed activated actions use Speed 1. An Ignition Effect uses Speed 1 during its controller’s own Prime or Regroup Stage in an Open Game State and cannot be used as a response.
(R-Effect)Reactionary Effect
The printed marker (R-Effect) always appears at the head of an effect statement, before its activation condition or other wording. It identifies that specific effect as Speed 2.
Use an R-Effect on either turn or as a response only when its conditions and a legal timing window permit, and complete its Cost before activation. It then follows the R-Link rules below.
Read each effect separately. The marker does not make every effect on the card Speed 2. Unmarked Trigger and Continuous effects retain their separate definitions; the absence of the marker does not automatically make them Speed 1.
Three effects, three timing cues
These excerpts come from existing starter cards. Each card's full text, conditions and usage limits still apply.
Ignition Effect Speed 1
Belle, Healer of the Eternal Pact · EP-SD02
You can target 1 Warrior-type Eternal Pact Avatar in your Vault; discard 1 card, and if you do, Manifest that Avatar in Defense.
You choose to activate this effect during your own Prime or Regroup Stage in an Open Game State. It cannot be used as a response. Targeting is the Cost before the semicolon; discarding and Manifesting are part of the Result.
You can only use each effect of Belle, Healer of the Eternal Pact once per turn.
R-Effect Speed 2 · Reactionary Effect
Alandra, Queen of the Eternal Pact · EP-SD04
(R-Effect) During your opponent’s turn, you can Expend this card you control; Manifest 1 Eternal Pact Avatar from your Deck.
The leading marker makes this effect Speed 2. Its wording limits it to your opponent's turn. At a legal timing window, including a legal response window, Expend Alandra as the Cost before activation; Manifest the Avatar when the effect resolves.
You can only use each effect of Alandra, Queen of the Eternal Pact once per turn.
Trigger Effect Event-based activation
Justin, Fleet of the Eternal Pact · EP-SD03
If this card is Manifested, you can add 1 Eternal Pact Vein from your Deck to your hand.
Justin being Manifested creates the opportunity to use this optional effect at the next legal trigger opportunity. You cannot freely activate it whenever you want. The event alone does not grant Speed 2 response permission; if it occurs during resolution, wait until that R-Link sequence finishes.
You can only use each effect of Justin, Fleet of the Eternal Pact once per turn.
Respond in the moment
The R-Link
When a legal Speed 2 card or effect responds to an action, it becomes the next R-Link. After both players decline to respond, resolve the sequence backward—highest number first, then continue to R-Link 1.
