If Spirit's Refuge is played on Fiora while she is Mighty, does she gain Deflect 2 (one from Spirit's Refuge and one from her own ability)?

Ruling: Fiora with a buff and Spirit's Refuge will only have Deflect 1, not Deflect 2. Spirit's Refuge's effect depends on Fiora's effect, so Fiora's applies first, and then Spirit's Refuge sees she already has Deflect and does not grant it again.

Sequence:

• Both Fiora's ability and Spirit's Refuge are continuous/passive effects that apply in the same layer
• They are checked during cleanup steps
• Because Spirit's Refuge's effect depends on whether Fiora already has Deflect, Fiora's effect applies first
• Spirit's Refuge then checks and sees Fiora already has Deflect, so it does not grant Deflect again
• Result: Fiora has Deflect 1

Nuances:

• This is a dependency situation where one effect depends on another in the same layer
• Timestamp order does not matter when there is a dependency
• The rules do not explicitly state how to order dependent effects, but the intent is that dependent effects apply after the effects they depend on
• Spirit's Refuge's wording "if they didn't already" creates the dependency on Fiora's Deflect-granting ability
