Hi,
I control a random Water shugenja, let's say it's Isawa Mizuhiko, and no other Personalities. The other player has Bayushi Saya in play and targets Mizuhiko with Saya's action. I play Reverence to Chikushudo searching for Touch of Ice, show it, attach it and gain 2 honor. What happens next? I'd say nothing since RfC is not performed by the targeted personality as it doesn't target between two colons, but I wanted to know for sure.
Relevant text: Reverence for Chikushudo Limited: Target one of your Shugenja. Search your Fate deck for a non-Unique Spell with an ability that has one of his Element keywords. Show it and attach it to him (paying all costs). Gain 2 Honor if this attached a Spell.
Bayushi Saya Political Open: Target a Personality. After the next time this turn his controller assigns him or an action resolves that he performed, his controller loses Honor equal to his Personal Honor, then he is dishonored.
