I tried to RNG a shiny type:null, failed for so many times, tried to adjust delay timings between 40-50 delays before the frame.
We're working on the proper method for Type Null - for now we've released a Tutorial for three of the four Tapus, as well as an Egg RNG Video Tutorial.
Lack of funds (and therefore the need to spend more time in real life) will make development slower, but don't worry, we're still doing what we can!
