Luckily, Jeff helped me out with the Han and Madine
I happened across the Saga End wave twice, as well as pre-ordering the case from NewForce. Found a total of 4 Hans, 4 Madines, and 2 Lando. That was it, and they all hit in the same week.
Looking back, I guess I was extremely lucky find as many as I did... and Brian was lucky I grabbed the extras that I did see.
