I recommend following your local Hot Topic on instgrom because they usually post when they have new pops. If that pop has a chase you want, then you should get there a couple hours before they open. That's how I've gotten a lot of chases (Gyomei, Twice, Hanako, Alluka, and Doctor Strange). It's also possible they they don't have any chases. The first two times my local HT had Gyomei, they didn't have any chases so I pretty much wasted 10 hours for those two days. They did have it the third time so I got it. You can also buy a case to get a guaranteed chase. I did that to get the Naruto Hokage chase and I kept a common and the chase and sold the rest to try to get some of the money back. Of course, you can buy one from HT, or Funko or whatever retailer has a pop with a chance at chase and just hope you get it.
