In what order do attacker and defender abilities resolve during a showdown, and how do layers interact with this timing?
Answered under Unleashed Rules FAQ and Clarifications
When a Showdown opens, the game first establishes Attacker and Defender and grants designations and Focus, then any Triggered Abilities that became Pending from those changes are added to the Combat Chain; during the Combat Damage step, Attacker assigns damage first using current Might. Layers (Ability-Altering then Arithmetic, etc.) are applied repeatedly to determine each unit's current characteristics (including Might) before damage is assigned or other effects that read those characteristics resolve .
Final Ruling
Establishing Attacker/Defender happens first (units gain their Attacker/Defender designations and the Attacker gains Focus), then the game adds any Triggered Abilities that became Pending to the Combat Chain . When resolving combat damage, use the units' current Might as determined by applying layers repeatedly until stable . The provided Core Rules do not fully specify the tiebreak for the order in which Pending triggered abilities from both players are placed onto the chain when they become Pending simultaneously; that ordering (and the general chain-resolution ordering) is not present in the supplied context and so cannot be authoritatively decided here (see Assumptions) .
Citing
01
When a Showdown opens, establish Attacker then Defender; give the Attacker and Attacker-controlled units their designations and grant the Attacker Focus .
02After those designations are applied, add any Triggered Abilities that became Pending from that change to the Combat Chain .
03If triggered abilities contain conditions or costs that occur later in their text, those parts are handled during finalization/resolution per the FAQs—i.e., some checks/choices occur when the trigger is placed and some when it resolves .
04Before assigning or dealing combat damage, determine each unit's current Might by applying layers in sequence and repeating until stable; Ability-Altering effects are applied before Arithmetic (Might) modifications .
05When assigning damage, Attacker assigns damage first using the summed current Might totals, then Defender assigns; once all damage is assigned it is dealt simultaneously .
Simultaneous triggers created by establishing Attacker/Defender for both players: the provided context states to add items to the Combat Chain if establishing caused triggers to become Pending , but does not specify how to order multiple Pending items placed at that same instant. The global tiebreak/chain ordering rule is not present in the supplied excerpts, so the exact ordering is unknown from these texts alone (see Assumptions).
Triggered abilities whose text contains additional conditions or costs placed later in the wording may split into 'condition' and 'effect' portions; the timing of player choices or payments may occur during finalization or resolution as clarified in and .
Effects that change a unit's abilities (Ability-Altering) can cause subsequent changes in arithmetic layers (Might) during the same re-evaluation; layers are applied repeatedly until no further changes occur .
Deathknell triggers: a Deathknell trigger is added to the chain before the card is moved to Trash, so the trigger will exist on the chain and resolve after finalization even though the source is about to be trashed .
Assumptions
The supplied Core Rules excerpt does not include the global rule that defines ordering of simultaneously Pending triggered abilities (for example, how to order items placed on the chain when both players cause triggers at the same instant). I assume that no additional automatic tiebreak ordering text is available in the provided context, so the exact placement order of simultaneous pending triggers is unspecified here.
The supplied context does not include the complete chain resolution/priority rules (e.g., APNAP or active-player/non-active-player ordering). I therefore cannot assert the precise order in which simultaneous triggered items from Attacker vs Defender are added to or resolved on the chain beyond what is directly stated in .
When a Combat Showdown opens, the game performs a specific ordered set of tasks: it establishes Attacker and Defender (units gain their Attacker/Defender designations), and the Attacker gains Focus. Only after those steps does the game add any Triggered Abilities that became Pending as a result to the Combat Chain . That means the designation and Focus changes happen before the game evaluates and places those triggers as Pending chain items. The rules excerpt does not, however, include a global rule for ordering multiple Pending triggers placed at the same instant (for example if triggers for both players become Pending when designations are set). Because that chain-ordering text is not in the provided context, the exact tiebreak for adding those simultaneous pending items is not authoritatively specified here (see Assumptions). The supplied FAQs explain how to parse trigger text into condition vs effect and when costs/choices occur (during finalization vs resolution), which affects when and how those triggers are placed on and resolved from the chain .
For combat damage, the Showdown uses each side's current summed Might and specifies that the Attacker assigns damage first, then the Defender assigns; after all damage is assigned it is dealt simultaneously . "Current Might" is determined by applying layers. The layers system is applied repeatedly until all effects have been applied and no further changes occur . Ability-Altering effects (granting/removing keywords or rules text) are applied in their layer before Arithmetic effects like Might adjustments are applied, so an ability that grants a keyword that affects Might or other arithmetic will be considered in the next re-evaluation pass if that grant changes numeric values . The example in shows how re-evaluation can cause abilities to appear or disappear as numerical values change.
Practical takeaways:
- Establish Attacker/Defender and grant Focus first, then place any resulting Pending triggers onto the Combat Chain .
- When resolving combat damage, calculate current Might by fully applying layers and re-evaluating until stable , then Attacker assigns damage first, then Defender .
- If multiple triggers become Pending at the same instant as a result of those designation changes, the supplied text does not define the tie-breaking ordering for adding them to the chain; consult the broader ruleset (not supplied) for chain ordering or use tournament/official judge guidance .
If you want a ruling for a specific cards-at-showdown example (for example, simultaneous "when this becomes Attacker/Defender" triggers from both sides, or an ability that changes Might during the Showdown), provide the card names and exact wording and I will apply the above steps to that concrete situation.
