Does Shady Spectacles copy Temporary from the chosen unit?
Shady Spectacles copies [Temporary] when the keyword comes from the chosen unit's card, its token definition, or a copy effect, but not when another effect granted it.
For example, copying Keeper of Masks gives the equipped unit [Temporary] because the keyword is printed on Keeper of Masks. If a unit has [Temporary] only because it received the keyword from Shadow's Call, Deceiver, or Mirror Image, Shady Spectacles does not copy it.
In rules terms, copy effects use copyable traits: a card's printed or already-copied traits, or the traits a token had when it was created.479.1.b479.1.b.1 A separate keyword grant changes what the unit currently has without changing those copyable traits.479.1.c479.3.a
