Just because they're immune to AAR doesn't mean they're good Domino counters. As @Kill_Grey mentioned, Archangel's actually a pretty crappy counter cause almost everything you do with him has an ability that can fail. That's when you take crit failure, when one of your abilities doesn't activate, not just when Domino's AAR prevents it form activating. For instance, Hyperion's Sp2 has a 60% chance to stun for 4 seconds. If you throw a Sp2 and it doesn't stun, you'll take crit failure. So you want to use champs that don't have many abilities that can fail. Hope this helps.
Off the top of my head mysterio is the only aar immune who doesn’t have a single rng trigger in his regular rotation, gulk can heal up the majority of crit fail damage, but in general people just use a corvus or ghost and burst her down, you take a bit of damage but she dies before it’s too much. If you’re a god tier Quaker she can also do it and take no crit fail damage
Mysterio gets AAR from magneto even as immune

Ghost can do it without triggering crit failure if you do only single hit mediums since she won't get unlucky and it is guaranteed to crit.
