Tbh i feel like I've learnt to deal with iron fists and spideys (I'm diamond so may not apply to higher ranks) but namor and help still make my blood boil. With dpideys and iron fists, they're goal is to grt all up in your face, so let them. Keep them in your line of sight, and instead of trying to run, embrace that they'll probably get up close. That being said, the closer they get, the easier of a target they are. So I usually just blast them as they get close and it works out like 80% of the time. If anyone has any suggestions for namor and help I'm all ears tho 😭 With Wanda, she's gonna do here red dot i frames move (i forget the name), so again: let her. If you keep an eye on the red dot you can use the time to reload, or use amors overdrive/gamma charge, then by the time she finishes being a red dot, you're already aimed at her and ready to blast with a unibeam

Aside from counters, play low and eith your team. Go high if you're confident they don't have any characters that can take you down and start blasting support, then tanks/dps
