Yeah the reverse four symbols technique is a nice fail safe to keep your bio from being stolen and or used at a later time by Kinjutsu users. I like the fact that it is a trigger activated jutsu but if you could actually trigger it yourself with a handsign just to help your crew proceed to the next land mark. That would be more entertaining and the people that you self sacrifice against would likely be bitter lol.
As for the next jutsu I have a few questions. Can this mark/tag combo be removed once placed.
Also if this tag causes disruption in chakra flow does that mean it would break a genjutsu?
It's got some nice qualities in that it makes any and all jutsu a +20 chakra cost on top of the current costs. Twice per battle with a 4 turn usage limit is also tip top.
Yes, even after placed, it's possible to remove it, much like any other tag. Given the mark is not applied directly onto your skin, but onto a paper tag, something which you can remove or tear apart with ease. And yes, it does work as a Genjutsu breaker, but you would logically take the damage that comes with the chakra disruption.
Very simple one. Perfect to use against Genjutsu specialists such as Ganmi or Kurama clan members. Unlike the previous one, this one takes effect immediately upon being placed on you, so it's harder to counter it, well, nearly impossible unless you know some unknown means of preventing it being placed in the first place.

So you make some clones, preferably distract your opponent and don't let him notice that you're forming this triangle around him. Once done, erect a barrier around them and immediately cause it to implode. Shooting them off much like Team Rocket
