Ossification exiles a creature or planeswalker for two mana — that's the whole deal, and it's clean. Light-Paws, Emperor's Voice can tutor it directly onto the battlefield off any Aura cast, making it one of the most efficient pieces of interaction that engine can fetch.
Best Commanders
Commanders with the highest synergy

Light-Paws, Emperor's Voice
Light-Paws, Emperor's Voice tutors Ossification directly from the library whenever you cast a smaller Aura, turning a two-mana enchantment into a free exile effect stapled to your engine.

Pearl-Ear, Imperial Advisor
Pearl-Ear, Imperial Advisor cares about Auras and enchantment payoffs, and Ossification slots in as a cheap, permanent answer that doesn't ask for anything beyond a basic land already in play.

Yenna, Redtooth Regent
Yenna, Redtooth Regent copies enchantments, and Ossification is a prime target — a second copy means a second exile, turning one removal spell into two with no extra mana.

Elesh Norn, Mother of Machines
Elesh Norn, Mother of Machines doubles enters-the-battlefield triggers, so Ossification's exile effect fires twice when it resolves under her, locking down two threats for one card.

Calix, Guided by Fate
Calix, Guided by Fate generates constellation triggers and puts +1/+1 counters on enchanted creatures, so Ossification pulls double duty as removal and a constellation proc that fuels his engine.

In Commander, Ossification is a staple-tier removal spell for any white enchantment deck — two mana to exile a creature or planeswalker is already competitive, and the land restriction almost never bites in a 40-life, 100-card format where basics stay in play. In Pioneer and Modern, it competes with more efficient options like Prismatic Ending and March of Otherworldly Light, but sees play in dedicated Aura and enchantress shells where the card type matters as much as the effect. Legacy and Vintage have cleaner answers at lower costs, so Ossification rarely makes the cut there outside of niche builds. Oathbreaker mirrors Commander's calculus closely — enchantment decks want it, spell-based decks skip it.
