By flickering text I mean something like this: FaZe Rain - 1 Million Subscribers Montage - YouTube or like this: FaZe Rain - 1 Million Subscribers Montage - YouTube
I've looked everywhere for this kind of style and nobody seems to either know what I'm talking about, or how to do it.
That is not an Effect that is applied, it is a combination of text on a 3D layer either tracked or carefully positioned to match the ground plane. Then a track matte using something like animated Fractal Noise is used to create the varying density in the text. The last step is a blend mode that blends the text with the layers below to achieve the color treatment you want. Something like Hard Lighe may work.
When you are trying to break down a visual effect it's important to take a look at the effect a frame at a time or pick out a still frame and then try and figure out everything that is going on in the shot. Very few visual effects are created with a single layer and a plug-in.
