Favorite ability in your main's kit?

What is your main's favorite ability to use in their kit? Or the most satisfying?

I'll go first. invisible woman's force push/force physics. I can't count how many times I've pulled/pushed tanks and divers to their demise. Grabbing a moon knight off of the balcony, and him getting completely obliterated so he'll stop throwing random crap at our team. Pulling in my tanks with an added burst of health so they can keep tanking with a bit of room and more health. SO SATISFYING.
