Type: Ground
Category: Special
BP: 75
PP: 16
Accuracy : 100%
Flags: N/A
Effect: 30% chance to badly poison.
Reasoning: STAB that spreads poison through a secondary effect, so the status spreading is locked to Natural Cure sets.
This moveset would be suited for a stat spread similar to Kyurem-Black (but probably not 700 BST), with higher Atk than SpA, where you would really want to go for physical sets but must go mixed most of the time.
On the physical side, you have no good Ground stab (only Bone Rush), and your physical coverage is suboptimal : outside of Dark moves, you only have access to weak moves, moves with double contact, or situational usage moves. On the special side however, you have way more options, with a good STAB in Earth Power, and Fire, Rock, Poison and other niche coverages options.
The similarities with Kyurem ends mostly there : the one missing option on the special side is a good Dragon stab (Dragon Breath is only 78 BP with Sheer force), but you have access to Dragon Darts for a really good no contact STAB to break special walls. Scale Shot is also another option for setting up.
So, for offensive sets, you have multiples routes to go with : Mixed Sets with Life Orb to break more effectively, full Special Sets with LO or Specs that makes you a coverage monster but needing to rely on predictions / super effective hits vs ground resists/immunities, or Physical sets with Loaded Dice, to exploit the good attack of the Sovereign but losing on either coverage power vs Fairies or resistance to status depending on the ability choice.
Status spreading is locked to the Natural Cure sets, that can spread poison using Calamity Quake (or paralysis with Dragon Breath if you want). Having the Sovereign spread poison is interesting because the usual immunities (Poison, Steel) are weak to Ground, so clerics/status immune mons/Covert Cloak could have a unique niche in the metagame. It also gives the Sovereign a way to hurt fairies on defensive sets.
As for the status moves, I went with simple stuff : Rocks, Corrosive Gas if you want item removal really bad, Court Change for limited removal, and most importantly Baton Pass, which allows the Sovereign to pivot but isn't a move that deals chip damage.
Baton Pass would also allow the Sovereign to pass speed boosts from Scale Shot to allies, which could allow for fun strategies and is balanced by the fact that the Sovereign must fast pivot to the ally, that the Defense drop is also passed, and that the Sovereign doesn't have any other boosting options.
BP is usually not allowed in most metagames, so having it only on the Sovereign would make it stand out even more.
The remaining moves are either options for support sets (Mystical Fire, Roar/Dragon Tail), priority for easier role compression (Sucker Punch), or niche moves that can be used by the Sovereign on more specific sets or teams (Terrain Pulse/Weather Ball, Reversal for Sub + berries / Sash + Scale shot shenanigans on HO, Venoshock to hit poisoned fairies on defensive sets)
