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 @ Rusted Shield
Ability: Dauntless Shield
EVs: 54 HP / 100 Atk / 96 Def / 136 SpD / 122 Spe
Adamant Nature
IVs: 0 SpA
- Iron Head (Behemoth Bash)
- Close Combat (STAB, but shouldn't be used often)
- Psychic Fangs/Play Rough (Fighting coverage)
- Crunch (can't learn anymore coverage moves for Fire or Ground, but this is pretty useful)

Zamazenta @ Choice Band
Ability: Dauntless Shield
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
