Yin is decent with Yan Lo, as is Toshiro.
But Toshiro really just becomes another buff support for Izamu with Yan Lo. He is simply too many points when you factor in Izamu and the rest of his crew. I still very much like the Drowned with him.
However, I really like him with Nicodem. His optional summoning is great, as you can let Nicodem have all the corpse counters, or just use all his actions to paralyze things, then let Toshiro summon a punk zombie then hit something. Plus his high cost doesnt' get in the way, as Nicodem obviously summons things, instead of just recycling them.
The combination of +2 Cb and +2 fate on the attack means your punk zombies will never miss, unless you flip the black joker.
(Trying to remember all this v1 stuff is making my head hurt. I've just decided to do the v2 stuff at GenCon, heh)
