Killing with mewtwo

[BugEye]

Hey guys,
First time posting on smash boards so idk the smash etiquette but I was wondering if there's many reliable kill options for mewtoo. So far Ive found full charge shadowball, f tilt, fair and back throw work well but they only kill at 140 to 160 while mewtoo can get killed by a heavyweight at 70 ish. Cheers

upthrow and upsmash are very reliable kill options as well. Also i'd recommend you to watch "mewtwo combos & tricks" by my smash corner. Even if its smash 4 most of the things apply to smash ultimate and there should be several kill-confirms in it.
