Here is the team I am using:

Itachi Anbu x x

Kurenai(full skillbreak) x x

Wind Main Shisui x

Talents are 3 2 1 1 1 with Shark/Flood Dragon summon.

For blitzing with wind main, I use:

Wind Main Shisui x

Itachi Anbu Fuguki x

Talents are 4 2 1 1 1 with Giant Katsuyu summon.

This team is prone to debuffs though, and if Fuguki is shut down at round 1, it will be difficult.

In arena, you can go with machine gun team:

Wind main Itachi Anbu Roshi

x x Fuguki

Talents are 4 2 1 1 1 with Giant Katsuyu summon. You can kill 1 or sometimes 2 ninjas in round 1 with this team.
