Does Fiora become Mighty when she receives a buff that brings her to 5 might, or does she need to be played with a card like En Garde to reach 5 might?

Ruling: A buff that brings Fiora to 5 might makes her Mighty.

Nuances:

• The question arose due to concerns about layers, but buffs applied to Fiora count toward making her Mighty when they bring her to the 5 might threshold.
