If you open up MVNActionFXTemplates.rpy, you'll see a list of transform definitions.
https://www.renpy.org/doc/html/transforms.html#transforms
I your script, you can apply these transforms to various displayable and images in your scene to produce the effects. The guide on the page here should help you figure out how to set each one up.
If you know which effect you'd like to use, I can give more specific instructions on how to use them, too, just hollar and let me know.
