DD6 Help! - Cosmic Nodes

I’ve been looking through a lot of post regarding what characters to use for DD6 especially the Non-legendary Cosmic nodes. I got my full Annihilator team for these cosmic nodes but they’re getting clapped. Who would be better choices with the new and current meta - Astral, Starjammer, or is it still Kang/Kestrel/ maybe Dormammu and other characters?
