Hi! It is very dependent on the team you are using. The reason why regular kabuto is so heavily used with immortal cancer teams is his ability to do a small amount of dmg to team. The damage he causes actually in essence buffs certain team members like Sailor Sakura and Kimimaro (among the other ninjas that can benefit) as they receive buff everytime they are damaged.

Play around with ninjas at your disposal and also search builds that always helps!

As for Shizune, she is okay when it comes to cancer teams as she does increase the healing for team and also increase her own damage caused by debuffs. However, if you have Original Kabuto that is usually your best bet!

Does his passive apply only 1 team that has Sound ninja or to all fields those have Sound ninja?

I find Kabuto's Leech useful when I'm using Kimimaro since any extra heals to him always helps, the only thing I don't like about Kabuto's change is the fact he can't buff Water Main when using Seal Reserve talent. But you can't really complain too much.

Kabuto no longer buffs Sailor Sakura after 3.0. He only uses his damage passive on curse mark ninjas like Kimimaro. However, he is still useful as Kimimaro is still a viable tank and Kabuto still has his summonable meat shields.

It's sad as I just got the immortal team just to survive in Arena a tad bit longer and annoy blitz team users who like to plunder me. But hey, at least I can still poison and chaos them, the only real counter against them in my arsenal.

And yes, it is Odd Della Robbia.
