I stumbled upon this on CoE #17:
Can I reveal Fled into Darkness on-guard when the Balrog faces a strike
of the auto-attack?
***You could if the Balrog is tapped at that moment. It does mess with the
auto attack (although in the attacked persons favour), so it is legal to
reveal it at this point.
If the Balrog is untapped at that point you cannot reveal it, because it
'directly taps a character in the company'.
It is true that you can't reveal a card on guard if it directly taps someone ni the company, so at a first look this answer is fine. However, the conditions of the playability of this card didn't exist during the m/h phase.
Fled into Darkness
TYPE: Hazard
CLASS: Permanent-event
Playable before the strike sequence on The Balrog facing a strike with a prowess higher than his. The strike is canceled and The Balrog taps, if untapped. The next time The Balrog would otherwise untap, make him tapped instead and discard this card. Cannot be duplicated.
Any thoughts on this one? Would you say the answer is correct?
