He said put it on a ninja that is immune. If you are immune to debuffs and you become immune to interruption you can't be interrupted on any way unless they remove before bee mystery buff.

@OP: your counter is normal kushina 3 stars + something that gives chakra with clones death. The 3 other targets of shark bomb are random so clones are a serious issues for those teams. An example of a good team that counters it is: normal kushina, kisame samehada, wind main and an immune damage dealer for move 1 like kurama naruto.

Shark is 0 damage on sasuke only that, anyways, get chaosed and poisoned (by koh).

The most deadly shark bomb teams rely on high combos not on direct combos.

An op team with water main right now is: kisame samehada, guren/angel konan, kurenai with koh and water style water trumphet (and doesn't even use madara or han).

The impairing controlling effects (sleep, chaos, acupuncture and immobile) are not enhanced versions of interruption effects.

When you apply a controlling effect you also apply interruption as a secondary unstated effect and this interruption effect is the same exact effect as the normal interruption (like minato hokage's or edo hashi's ones).

On an immune to debuff ninja a controlling effect behaves exactly as an interruption effect, so if the ninja is also immune to interruptions he won't be interrupted.

P. S. I cannot believe you do not remember the time when root of warrior mb + mifune was a common meta and the only way to remove buffs were skewering and sand dust.

P.P.S. Bee's yo! effect is a buff and gets removed by buff removing effects like shisui's mystery, skewering or han's, maybe you got tricked by the fact you use shisui mystery and still interrupt them with that chaos, because firstly shisui mystery removes the buffs and then apply chaos. If you use a buff removal effect you actually remove or bee or root of warrior/flower guard/guidance so the target ceases to be or immune to debuffs or immune to interruption and so gets interrupted for that reason but try to use a controlling effect without buff removing effects on a normal hidan or mifune with root of warrior or on a tendo with guidance and you see how you interrupt it.

Hm... That's indeed weird. I am sure in 4.0 worked thar way, but maybe with 5.0 the mechanics changed, considering what happens with shark bomb and the chakra stealing even if the mystery were queued.

With 5.0 the way this mechanics work changed. Now, if you apply a debuff after the standard attack of a ninja (so the situation where it carries on the following round) it getd actually casted again before the action of the ninja, so the control effect gets rolled again and can indeed fail even if in the previous round went off. This happened because people abused on this fact since was not supposed to work that way from the start.

Yep. But this is so since 5.0, because the mechanics of interruptions changed because the lenght of the action itself and how the effects are queued changed (is an indirect consequence of the fix they made to overcome the issue of the mystery delay issue we all experienced in 4.0 that now, thanks to it, almost disappeared).

In 4.0 shisui was able to interrupt an itachi susano'o with bee mystery because the 'action' was one and was preset so firstly he removed debuffs, then he applied chaos.

With the current modification before each action there is actually room for an action and a preaction. Interruptions are designed now to go in the preaction so an effect like shisui mystery now gets actually split in two and the interruption goes in the preaction while the removing debuff effect goes in the action, as before, with the consequence that itachi, now, can't be anymore interrupted.
