It's a troll team in this sense: A serious team utilize ninjas that are interconnected in certain ways, often buffs one another. It is setup in a way that gets the best dmg and cc output, and can nullify opponents attacks as well as protect itself. Here, all ninjas are not at their usual optimal position (explanation below), They are all over the place, sure Chiriku provide a buff, but that's pretty much it. The dmg is meh, the tankiness of the team is mediocre, and it's ridiculously easy to counter it, yet it still won against teams after teams that are suppose to counter it, so that's why I called it a troll team.

As for positioning of the ninjas:

Chiriku is not often used as position 1, he lacks the tankiness and his dmg is mediocre compare to other position 1. His cd is also super long, it can be reduced if atk, but if he used mystery in the round and dodges atks, he's not much use -> unreliable as position 1. More often than not he can't even use mystery round 2, which mean if opponent even have half a brain and knows how these ninjas work, this team would be dead by r3 easily. Thus why people usually have Chiriku in any position but position 1.

Sasuke is great, but he's used more in position 1 than 2. He's usually only position 2 when position 1 is someone better (like 6PN for example), which as explained above, Chiriku isn't.

Kisame simply doesn't contribute much to the lineup, aside from stealing chakras, which can easily be countered if he's cc/paralyzed, and having him as position 3 means this would very likely happens. -> unreliable support.

The talent I have on Fire main also doesn't really contribute to anyone but Fire main himself. -> so he's a position 4 support but doesn't really do much supporting.

So basically I had a non-tanky tank with a long ass cd, a benched dmg dealer, and 2 supports that can easily be cc-ed if my opponent knows what to do, so basicailly, it's unreliable and easily countered if any of the ninja is under a hard cc, the chase falls apart, and the team falls apart. The only thing this team has is super armor, res buff, and consist of events ninjas (and as we all know, a team consist of all rare ninjas can still be horrible and ridiculous).

It's also a troll team in the sense that Konan Taisho (position 1) - Edo Deidara - Jinpachi - Wind main is a troll team. I'd never use it when winning or losing actually matters, like for example, ranked arena, space time, or even Zenith if they ever all appear in there someday.

Also, trolling can sometimes be defined as causing frustration using ridiculousness. So, there's that.
