Does Mask of Foresight trigger if a unit ends up attacking alone mid-showdown (e.g., when starting with 2 attackers but one dies before damage)?

Ruling: Mask of Foresight only triggers when a unit gains the Attacker or Defender designation while alone. If a unit already has the designation from when the showdown started with multiple units, Mask will not trigger even if other units die and it ends up alone.

Sequence:

• When a showdown begins with 2+ attackers, all units gain the Attacker designation
• Mask of Foresight does not trigger because no unit is attacking alone at the moment of designation
• If one attacker dies before damage, the remaining unit already has its designation and won't trigger new Attack triggers like Mask

Nuances:

• Mask CAN trigger mid-showdown if a unit gains its designation while alone (e.g., being moved into an empty battlefield as a defender)
• "When I attack/defend" triggers happen when units are assigned designations, not just at showdown start
• Mask can trigger multiple times on the same unit in one turn if it participates in separate combats while alone
