Just don't overthink it. It is very easy. I used Moleman, Spider-Woman and Captain Britain for my run.
I was able to run through it pretty easily.
Mostly used FAM with the following hacks: second chance, stun after special, and armors increase stun duration. So a lot of the fights was basically stun lock punching bag cheeses.
I think Viv would also work with those hacks.
It’s not too tough - even I who suck at Incursions was able to complete all 15 zones with minimal investment. I used Molegod, SpiderWoman, and Jean Grey.
You can go for the armor / stun lock strategy, or a fury-centric strat with Swoman, or you could even rock the bleed»power sting strat with Moleman.
Watch out for Peni bosses. Not a lot of good Peni counters in the saga pool. If you catch a nasty set of nodes, she can definitely slow you down. But overall it’s still quite easy.
I primarily used Venom - with him as a Herald, with Odin buffs, and then the “bleeds give them power stings” and any smaller hacks that increase bleed and power sting damage. He just melts people. Also had Okoye and Silk on my team.

None of those are saga champs for incursions.
Rank 4 Howard the Duck. Light work, free healing and massive special attacks from all the prowess. Did struggle a little bit against stun immune air walker though but in the end it only took 2 revives
Wait I did not notice that they reset incursions lol. I could've sworn my timer still had another week it was counting down. Whoops.
