Kyuden Kyotei - Discarding a Ring

Political Reaction: Even if this Stronghold is bowed, if you control the Imperial Favor, before a Fate card out of play turns face-up from an action, trait, duel, or from being discarded: Give the card +1 Focus Value when it turns face-up.

If I were playing a ring, and paying it's cost by discarding it from hand, would I be able to trigger Kyuden Kyotei, as the cost of the ring is to discard it?

This is one of these questions that looks so obvious that I wonder what if I am missing something.

Nothing seems to prevent it.

But again, I feel like I must be missing some sort of context for why this is a question.

The Question was if you can use Kyuden Kyoteis reaction during the discard of o a ring to pay for it being played. The answer was affermative.

Since you are playing the ring wouldn't it be face up before the discard? That seems to prevent it.

Ah, I see the point. Thanks for the catch. That said, you're then turning a card face-up for an action, and can use the stronghold for that part of its trait. It doesn't say "effect of an action," so discarding for a cost would also seem to fit its criteria. The net effect seems to me to be exactly the same.

Again, there may be some context I'm missing as to why the "discard" part is particularly important.

It semmes that the answer is in contradiction with the explication that have been given explaining the erata of Kyuden Kotei. viewtopic.php?f=59&t=70472

precisely those parts:

Starting from 1 October 2008, Kyuden Kyotei will read (underlined text is new):

Your Market holdings in and out of play have the Legacy keyword. Political Reaction: Even if this Stronghold is bowed, if you control the Imperial Favor, before a Fate card out of play turns face-up from an action, trait, duel, or from being discarded: Give the card +1 Focus Value when it turns face-up.

(...)

It will no longer be useable: * when playing an Action card, because the turning face-up is from the rulebook, not the action itself; * when playing an attachment, again because the turning face-up is from the rulebook (sorry, there is no more Kyotei/Yarijutsu combo); * when taking an action on a face-down Ring or other card in the hand; new additions to the Comprehensive Rules (Using abilities on non-Action cards from the hand) clarify that the process of taking that action turns the card face-up before it is discarded or enters play.

bolded text is mine.

The Ring is turned face-up by the rulebook before you announce which ability you wish to use. See Using abilities on non-Action cards from the hand: Sometimes, through card text, an ability is able to be used from the hand even though the card it's on is not an Action card; for example, the "discard from hand" cost on a Ring's ability, or a Follower whose ability puts itself into play from the hand. When such an ability is used, the action must be legal to take in Good Faith (see Good Faith Rule). If it is, then the player turns the card face up in his or her hand, then announces and takes the action. If, when the action ends, the card is still in the hand, it turns face down again.

Thus, Kyuden Kyotei's Reaction may not be used.
