It's just an assumption, and it sounds somewhat reasonable. The Chinese New Year is over, so it may be. But those items are still in stores so who knows. But I haven't seen or heard about anyone getting one recently.
Took me like 15-18 magics before I got a pin... After that I got like 10 pins out of like 30-35 magics. I've been on a miss streak on my last 10 or so magics.
Luckily one of my first couple pins was a Mushu pin x_x
