Ok I have played 2 games as Phoenix with Crane splash Voice of Honor and Noble Sacrifice versus Dragon. Now my experience was I played only one Voice out of 2 games and I drew and held them in both games. They were just dead cards in hand. Now again I didn't see any Asako Diplomats in either game either. But i did draw Court Games fine. It seems the Phoenix cannot reliably honor more than one here and there. Not enough to run those splash. If your opponent denies you the fire ring it can hurt. The Kimono is good but it is only good on someone with fate. It doesn't help you win a conflict. It is an investment later. So you have to win conflicts with the Kimono, Asako Diplomat, and the Fire Ring to get honored. The trick is getting on that positive side. I think keeping Phoenix on the ropes will be key to beating them. To that end, I think Phoenix has to drop some of the ring tricks and play more "win conflict" cards. Less Know the World and maybe not 3 Way of the Phoenix, and run Rout and For Shame! that you didn't have room for in your deck. Even Display of Power might only need 2. After you lose 2 provinces, not defending a 3rd doesn't look like much of an option.
Going back to splash, I am thinking after Crane not working so well that I agree Dragon would be good. Mirumoto's Fury is amazing. Let Go helps remove pumps so that wins fights. The Tattooed Wanderer is good too. Otherwise I think Lion to counter For Shame! And Mirumoto's Fury with Ready For Battle and Honored Blade for more pump.
Just my thoughts after playing them.
