Might be a bit of topic, but I had my first experience with intention manifestation stuff through a RNG. Steve Pavlina posted a message on twitter quite a while back saying he was intending more abundance for anyone that reads that (something like this can't remember the exact message).
Right after I read that synchronicities started going off like crazy and I won two poker tournaments in a row. Anyone who plays regularly should know it's pretty tough to final table two big field tournaments in a row let alone win them. I also won a few hands where I was a massive underdog. While that isn't too special the syncs that were going off at that exact moment freaked me the ♥♥♥♥ out and I kinda had no idea what to believe anymore lol.
So while I did not affect it at the time it was a starting point for me into looking into this stuff and I've had some success since. The only problem has been consistency when it comes to RNGs based on my journals it is very hit and miss.
