I use the a standard LM Shisui team. 1/4/1/1/3 with Serpent as chase and monkey king as mystery

X X X

X LM Kushina

Itachi anbu Shisui X

The variation of LM at sec place instead of third is to stop the barrier of Madara five Kage, which is becoming common in pvp. Kushina's attack causes paralysis which can lure out the mirror of Kurenai or fire main. Wind/Water main is often put at third or forth place, so it's not a problem for Shisui to stop them from refresh or healing. And this team has a high single target damage if Kushina get's to use her mystery before shisui attacks. The only problem now is that water chaos team, but I think that's a pure initiative stack problem
