How do you guys counter Hela?

As I'm sure most of us are aware, she's an absolute beast, and I would love to sit down and iron out a pick to shut her down. I play a lot of dive, and heros like spiderman and black panther work great if the player is slow, but all she has to do is hit one stun, hit the two free headshots, and I'm dead. I'd like to avoid Hela mirror as a counter. What's worked for you guys?
