how to sync animations correctly

[quaint quartz]

So i am making a battlegrounds game and im not sure how to sync all the animations. Because i've tried starting it local and then sending it to server, but this is not syncing at all. I've tried also to do a remote event and having then the animation starting local, but this is also not syncing correctly. What is the best way to sync the animation, so like a attack animation and a hit animation...
