A player, 27 July 2010
Only Actions Speak 0 GC Reaction: After an action is announced: Negate all Honor gains until after the action's resolution. At that time if this negated any gains, negate all Honor gains until the end of this phase and draw a card. Battle: Choose your performing unbowed Personality: Bow a target enemy card with lower Force and without attachments. Bow its unit if your Personality has 7 or more base Force. 1 FV
If a copy of Only Actions Speak has already been played for its reaction this phase, and a second copy is played in response to an honor gaining action what copy of Only Actions Speak causes the negation of the honor gain? The first card? The second card? May the player draw a card because of successful negation? Does the active player choose which card effect causes the negation?
Because of the timing, after an action is announced but before the effects occur, is this considered a successful negation by the second copy?

I'm going to assume that the first Only Actions Speak in your question negated a gain before end of the resolution of the action whose announcement triggered it, thereby creating a new Honor-negation effect that lasts until the phase ends. So, along comes another Only Actions Speak creating another negation effect that lasts until another action's resolution ends.
Now, despite expiring at different times, both these negations come from Indefinite Conditional Effects and both have the same trigger, so the active player would decide which is applied first. If he decides the first Only Action's Speak's negation is applied first, the second's negation would then do nothing, and no card would be drawn. If he decides that the second's is applied first, then a card would be drawn.
Because of the timing, after an action is announced but before the effects occur, is this considered a successful negation by the second copy?
Sorry, I don't understand this question, but I hope my above answers cleared everything up.
