I think a unit with ~800 ATK and a matched orb can kill her if you're using a 6.25x ATK multiplier.
So a Slasher team with an evolved Kuro, a 2x Ace team, a Killer or G3 team should kill her.
If you don't have them, just use a Helmeppo v1 or other defense reducer and call it a day
My DJ Sanji has 680 ATK and i did about 13K damage on her with a matched orb, enough to onehit her after his special.
Double Ace of course.
