Kushina, Bee, Sailor, Water.

32232 - Lightning Tiger.

Kushina, SB Kurenai, Sailor, Water

32232 - Koh

I like and hate Kurenai one. If you can't blitz Kushina out, probably you would lose. Too much healing.

Massively weak against hard hit blitz and ignite, especially Madara blitz team.

I used to run

Light, Kushina, Bee, Roshi. Lots of debuffs and immobile for cc.

24211 - KOH.

Do people know if her mastery's effect can live past the round she casted in?

For example, if you Masked man a ninja in round 1 after that ninja had used up the standard move, the immobile lives through to round 2.

Does the debuff from Kushina act the same?

Thanks in advance

No only lasts for 1 round. You can see this when you suppress ninjas that are immune to debuffs (roshi, kcm naruto, etc.) they will get back their immunity the next round. The key word is "suppress" rather than "remove".

Hot Kushina, the ninja that preys on immune ninjas. if you can keep her alive and use poison tai or KOH you will get a high win rate.

If you actually read the chinese description of the immunities says: 'before the first action in a round this unit becomes immune to debuffs' that's why on permanently immune ninjas like roshi the immunity goes back the following round. Here we got the meh translation so is not that clear.
