Extra audacious idea:
Menka, Henge into a scroll! While carrying a scroll! We will steal someone else's scroll, replace them with you, and you shall pop open, beat them over the head, and knock them out at the gate! Or replace Menka will a scroll by moving too fast for the chunin guys to see.
We need to do better than [I[that[/I] though...something more, something fresh and new. Or as fresh and new as we can manage.
How big is the detonation range on explosive tags? As in, how far can we be from them to trigger then, if we were to slip an explosive tag note in the scrolls?
It's more blatant sabotage, but eh.
Lemme think, how many examiners are there? Two or three? If two, Akamaru and Menka can replace Kiba and Ino, or Ino poses for Ino and Menka. IF we can arrange for us to get our scroll last and an earlier Konoha team can smuggle our allies into the booth, we can screw people over more freely. Then, us being the last team to enter, we retrieve whoever we sent in.
Team Gai is frankly probably the best choice for a swift and silent take down, with Neji and Lee. But Neji disapproves of our style and Tenten just doesn't like us. Hinata, Shika, and Chouji are next up with Shadow Binding and Gentle Fist. In fact maybe even superior in certain regards. A number of them, come to think of it....
But we'd need to make sure no other sensors saw through this.
Still, it's another exam hijack if we pull it off that favors us quite a bit.
