Does a unit buffed by two Spirit Refuges have Deflect 3 (stacking Deflect values)?

Ruling: No, Spirit's Refuge does not stack Deflect because it says "they have Deflect if they didn't already." This prevents multiple instances from the same source from stacking.

Nuances:

• Rule 721.2 allows Deflect to stack when granted by multiple sources, but is currently designed for future-proofing when more Deflect cards are added
• The "if they didn't already" restriction in Spirit's Refuge's rules text prevents stacking
• This differs from Green Lee Sin's buff stacking because Lee has ability text "I can have any number of buffs" which overrides the usual restriction
• If Spirit's Refuge did not have the "if they didn't already" clause in its rules text, then Deflect would stack
• Restrictions in reminder text (in brackets) do not function the same as restrictions in rules text
