If Yi is on Reavers Row with 2 defending units, one unit moves to base via Reavers Row's ability, does the remaining unit get Yi's buff before combat damage?

Ruling: Yes, the remaining unit gets Yi's buff before combat damage.

Sequence:

  • Attack is declared on Reavers Row where Yi is present with 2 defending units
  • One unit moves to base via Reavers Row's ability
  • Yi's continuous effect applies to the remaining single defender
  • Combat damage occurs with the buff active

Nuances:

  • Yi's effect is a continuous effect that applies constantly whenever there's only one defending unit, not a triggered ability
