Beating SpiderGwen

I am having trouble doing a 100% of chapter 1 of the Master EQ. I can get to the end with pretty healthy champs but really struggle to beat the SpiderGwen boss that regens. I have been able to beat her twice with Venom but have had to use lots of potions. I think my team is good enough, but my skill level and knowledge may not be high enough yet. Does anyone have a video or tips of how to beat Gwen with Venom or any of my other champs?
Here are my best champs (they are all unduped):
Venom 4* r4
Corvus 5*r2
AA 4* r4
Vision 4* r4
Omega Red 4* r4
Ghost 4* r4

Yes, my trouble is that she keeps gaining so much health. Whenever I bring her down she does that spider jump thing and regens like crazy. Umberto, what do you mean by "eat her regen with your sp1"?
