It seems like a good bit of us may have missed out on a single rare for each of our supers.

I ended up missing Edo Zabuza, and drew everyone else a decent bit of times.

Zetsu-1

Ameyuri-2

Jinin-2

Mangetsu-2

Jinpachi-3

Kushi-3

Sizori-3

Zabuza-0

As Steve and Random said, it's mainly and rng-based thing.
