How do I animate in with one effect and animate out with another? (I'm asking for editing text)

I have a line of text animating in using 'fade up words' and would like to change the opacity to 0% a few seconds later.

I tried adding the 'fade up words' effect to the text, and then adding the add > opacity, which created an 'Animator 2', but when I added 100% opacity and then faded it to 0% later, the 100% opacity would override the 'Animator 1' 'fade up words' effect.
