Support Pokemon for Tera raids recommendations please

I just started playing SV and got into the tera raids. I really like playing support as I just find it fun to be that guy denying the enemies kills with heals and statuses. Currently I've built a blissey for special and a grimmsnarl for physical. I still feel like i need to expand my support team as grimmsnarl is weak to steel and cannot heal. I'm looking for a physical support mon that can heal or just a support mon able to do something slightly different that counters a different type of raids from the ones I already have.
