Answer 1

Zamazenta-Crowned @ Rusted Shield
Ability: Dauntless Shield
EVs: 252 HP / 252 Atk / 4 Spe
Adamant Nature
- Behemoth Bash
- Close Combat
- Play Rough / Psychic Fangs
- Crunch / Metal Burst

Dual STAB, and your choice of attack to hit fighting types. Crunch is just another coverage move, or Metal Burst can be used for Zamazenta's big bulk.

Answer 2

Zamazenta @ Choice Band
Ability: Dauntless Shield
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Play Rough
- Crunch
- Psychic Fangs

Has the surprise factor of being able to 2HKO Unaware Quagsire without critical hits, unlike both Zacian forms and Zamazenta's Crowned Forme.
