How would I achieve an FXs like this?

Hello!

I am in the middle of a project, and I want to recreate something like the dash FX in this game (the smoke on the ground).
I have not done any effects like that before how would u guys approach it?
Especially how it fades away.

You can go 2 ways. Both require handdrawn most likely.

  1. Create an animated flipbook.
  2. Draw a still image of the smoke and then on top of it draw a gradient for dissolve!

it game me the illusion of being a mesh that gets replaced and then at then a drawing of the end fading of the could.
