The best offence

is a good defence... just kidding.

The best part about Azure Fang is that she's super versatile with her passives, so you can make a lot of different teams with different strengths and weaknesses. I don't agree that her mysteries are the best, but... well, I guess everything else wins out.

Midnight's bloodthirsty demon always has me biting my fingernails, especially if you've got a strong offence-weak defence character like some of the jinchuuriki, that can't use mystery on first turn.

Clone spam is definitely annoying, unless you've got a strong, whole team wipe out move like Kage mysteries or some other clone killer. High float repulse chase with Pakura though... *shudders*

Scarlet was my first ninja, and he's got a soft spot in my heart. Used to use him all the time with Hinata, Sai GNW, Ino GNW, and rhino, which was my first summon (Killer chaos team). Alas, it stopped working since all these new nins came out and I had to face people who were stronger and had better ninjas in general. A lot of ninjas nowadays are immune/can be made immune to sleep, so it's a shot in the dark to use the feather illusion standard, which I consider to be Scarlet's best standard (bomb blast dance is second best). The clone double move thing is great, but the clone never lasts long. Oh, they changed death mirage. Huh. That's handy.

Have never used Crimson once, so I can't speak for him. Saving him...
