Buero could possibly beat me if his Sketchy has an unlocked SA2 (to combat my Bloodbath) and if his BHD has ~100% block proficiency and a tag out equipped. I'm still doubtful, though.

EDIT (March 19, 2019):
I take it back, apparently it's extremely doable.
Thank you Buero for opening my eyes to Sketchy's SSS-tier support.
