Faced her 5 times in uncollected now, shes not too bad, here is a list of champs that should be good to take her down from my experience... (armor breaks are the main weakness for her)
Corvus - Armor break on his parry and overall great damage, effectively making you not need to worry about the stun immune indestructible! (careful though after 20 hits he is a wet pillow)
Medusa - Her medium attack instantly takes away her indestructible and its easy to keep them up, if you can armor shatter her its just a normal fight basically
Yondu - Armor breaks on his arrows, steals the armor for himself, if duped he cripples her special damage too
Sentinel - Armor break on his sp1 and generally a great counter overall, plus with his advantage he builds analysis charges quickly
Stark spidey - Great damage when you build his poise charges but the main thing with him is his ability to reliable save you if you fail to dodge the reversed specials
Spiderman symbiote - Highly underrated option, if you can land a heavy attack you can armor break her and stop her other form for 80 seconds!
Juggernaut, Unstoppable colossus, magneto - put these together as they are all immune to her telekinetic abilities!
Other options i can think of include hyperion, iron fist and king groot (permanent armor break on sp1)
I've found a great way with her specials if youre uncomfortable dodging the reversed specials is block or try and parry the first hit, dash forward to dodge the second then immediately dash left to counter attack. or if you have good reactions its fairly easy to dex both her sp1 and sp2 by timing 2 dash forwards and you have time to punish if you immediately swipe left after dodging the second hits, her heavy attack is also one quick hit but relatively easy to punish
if theres anyone i missed please do add them underneath! hope this helps at least 1 of you
(havent fought omega yet but heard Gulk, Void, morningstar and vision are good for him...)
