CC / Ice Fang / Crunch / Psychic Fangs combined with a choice band or life orb lets Zama-H 1-2HKO everything in the tier off of a read, except Clef (and Tangrowth in the case of life orb). Zamazenta-Hero also has 92/172/115 bulk which even while uninvested is comparable to defensive Corviknight, bar the typing and recovery. A scarf isn't necessary either since zeraora and dragapult are the only non scarfers that outspeed anyways.
Combine the above with basically any support and you'll punch holes in teams.
