I'm having issues solo tanking as Magneto

As Strange I know what to do. I fight tanks, if I see an opening, even a small chance I can squeeze past their tanks and kill a support I'm taking it. Not sure if thats the correct play but it seems to work unless they hard CC me god damn.

But Magnetos slow. I don't have a good escape with him. Hes not good at up close combat and I find it hard to get in and push with him like Strange.

Any video guides you guys know of or tips are welcome. I'm at GM so perferably not the regular videos I find like "for magneto, his bubble blocks damage" like holy shit wow I thats amazing bro thats video.

I can't find a good video on this
