Kurosa Event Dungeon Team Help

As the title says, I need help pushing the event dungeon (stage 16 at least, hopefully 20). Im currently stuck at stage 15 and going for the fusion. Hate plarium adding this as a fusion requirement knowing how overtuned it is.

Is there any champs in my roster that will help push the dungeon?

My current team is a really slow clear consisting of Geo, Gnut, Artor, Rector and Stagknight but it cant push any further...
