Spy tool for website to find push landing

I am promoting online casinos and I found a casino that’s already largely successful in their mobile ads campaigns. I used similar web to find that a majority of their traffic comes from mobile traffic, which I assume to be push/pop ads.

My question is if I have a specific website/casino in mind, is there a spy tool I could use to find what landers they are running for push and pop. I tried affbank but I found it’s hard to target specific casinos and it only works by key word.

If anyone could help it would be much appreciated

Anstrex maybe, they got a 2 day free trial so you could figure out if offers what you need without paying.
