^- all of the above arguments, plus some.
To go back to my cloud, Dart was wrong to argue on my behalf. He wasn't wrong to draw attention to the fact that a) if I had summoned the cloud as opposed to have gathered it, they would have been metagaming by noticing it was different b) they assumed it was Kirisame (Renkai said Kirisame in his post, and Sabu assumed it was water, both of which were not my intention.)
I talked to Bocchiball about this; got it straightened out pretty well, I think. Sabu's sealing method will fail in my post because he said it was a water sealing technique. Bocchiball tried to say it was a generic sealing technique, but... if that is the case, well, I wanna know this technique so I can go around and spam it on everyone, sucking up everyone's techniques into nice little scrolls no matter what it is made out of.
Next, Hazama. I too contest that he is even able to summon the Mazo, and I also contest that he is entitled to ignore the damage received from the twins. Even if he is a Jashinist, that doesn't mean he regenerates; further, I've seen the effects of concussive force against tempered plate steel armor on ballistic gel torso, and it isn't pretty by any means. Hemorhage and concussion (leading to delirium, confusion, and inability to focus or coordinate mentally or emotionally) are both common things I saw in the tests I conducted years back. Bone and steel are different, sure, but Kimimaro's bones were stated to be as strong as steel. Bocchiball gave me two examples where Hidan "tanked" techniques, but neither of them were a combination technique, neither of them were point-blank, and neither of them were as focused as the twins' attack. So, that's my argument for that. I want to see Hazama either a) dodge the twins' attack somehow or b) suffer his concussion, hemorrhage, and be so confused and delirious that summoning the Mazo would be impossible anyway.
Further, now that I think about it, it was pretty clear that me, Sakuren, Rinoa, Saino, etc are all out of sight enough from the battle that only a Byakugan could be able to actually find us; but determining us as such from the civilians would be a nice try. With all the buildings and such breaking up that Sage Mode Wind, how did Hazama get blown all the way to my position in such a way as to be able to summon the Mazo and auto-find me and my merry band of manslayers?
The Mazo even being summoned is another issue. He claimed to have borrowed resets from another account, which isn't okay in my own personal book. I haven't seen him openly train his skills anywhere, though I guess you could argue I haven't looked everywhere. Further, in the Manga, there is only supposed to be one true Rinnegan, which means only one true summoner of the Mazo. Madara is the exception to this with Sasuke gaining the Rinnegan because they are both reincarnations of that one brat of the Sage.
Then there is the issue of Edo Tensei jumping into a living body. I'm in the opinion of a definite no, but technically speaking, I haven't found anything that says you can, nor anything that says you can't. Further, I wanna know the person he jumped into. I wanna see proof of it all.
I also want to know more specifics about this lightning-like chakra blasts; I have a Byakugan which would be able to identify everything about the chakra nature, type, etc of this blast and would be able to direct my countering to it, if the summoning is legal. Which I do not propose that it is.
Without certain rules over the RP of the Rinnegan revolving around recent Manga developments, I don't see how we can feasibly say that Hazama has a true Rinnegan and is able to summon the Mazo. That needed to be determined a month ago; determining it now, even in Hazama's favor, is metagaming.
Anyway. We determined that we were going to ask Takara to be the judge on the battle. She is known for her neutrality. We'll see what she says on the matter. I'll see if I can't direct her to this forum post; other people should probably do so as well, because I am incompetent when it comes to working the forum.
