Hmm, looks like I'll either stick to the old Impenetrable Barrier quartet, no Doki or Kimi, or possibly those Chakra Eater ones you mentioned. I'll have to look them up to be sure.
Beyond that, I'm trying to think of some good cards to put in. I remember getting advised to use that Flower Shuriken jutsu before, and of course some of the Sound Four stuff, like that Mists jutsu, and the one to get it back. Also their actual Barrier, and maybe one or two copies of those Gate cards?
Hmm, beyond that, not sure what missions would be good. I forget which version of the Power of the Curse Mark (or whatever it's name was?) was the good one, but that would be in. Hmm, I still kind of like that Research Into Forbidden Techniques (again, whatever the name was...) that shuffled Jutsus back into the deck.
Any advice? I'm hopefully going to be ordering some cards in the near future, and I'd like to know what I might want to aim for. (I do already have one or two copies of each of the Impenetrable Barrier ones, though the only Stage one I have is Stage 2 Kido I believe. Plus two of their Barrier jutsu.)
