Need help with TOA hard 80 - Seara (with new buff)

Thanks to that godamn buff this stage has suddenly become a nightmare. This is my monster box. Any suggestions? : http://i.imgur.com/kbT0H1j.jpg

My strategy so far: The bomb kills me so ive been running baretta spectra verde chasun veromos to try and not give seara any turns. The closest I got was killing all the mobs but losing chasun and vero so it was spectra verde baretta vs seara and I got her to about half hp but died. If baretta misses an atk bar reset or spectra doesnt get to slow its pretty much GG unless it gets resisted which happened a few times but basically i dont think i can RNG my way through this. Is there any better team i can run? I thought about an immunity team with maybe chloe and draco but I dont think i will have enough cc for the mobs and earlier stages
