Omnath, Locus of Mana turns your green mana pool into a permanent stat — every floating mana grows it, and that mana never empties at end of step, so you can stockpile across turns into a Ghalta, Primal Hunger-sized threat that also swings. If your deck wants to accumulate and spend green mana in large bursts, Omnath, Locus of Mana is the reason Yurlok of Scorch Thrash pilots run it in half their lists.
Best Commanders
Commanders with the highest synergy
Yurlok of Scorch Thrash
Yurlok of Scorch Thrash forces mana burn on all players, and Omnath, Locus of Mana converts that extra green mana into raw power instead of life loss — making Omnath the card that turns Yurlok's punish-the-table engine into a personal advantage engine. Showing up in 50% of Yurlok of Scorch Thrash lists is no accident.
Fangorn, Tree Shepherd
Fangorn, Tree Shepherd generates green mana whenever Treefolk enter or attack, and Omnath, Locus of Mana gives that mana somewhere to live between combat steps rather than disappearing. The two cards together mean Fangorn, Tree Shepherd decks can snowball their board presence across multiple turns without losing surplus mana to the void.
Selvala, Heart of the Wilds
Selvala, Heart of the Wilds can produce explosive bursts of green mana from a single tap, and Omnath, Locus of Mana banks all of it, growing into a massive beater from the overflow. The combination lets Selvala, Heart of the Wilds decks go from engine to finisher without needing a separate payoff.
Ashaya, Soul of the Wild
Ashaya, Soul of the Wild turns creatures into Forests, which means every creature entering the battlefield can trigger land-based effects and generate mana — and Omnath, Locus of Mana soaks up everything Ashaya, Soul of the Wild produces without losing a drop. The pairing rewards you for going wide with creatures while also threatening lethal commander damage.

Commander is where Omnath, Locus of Mana is most at home: the longer game gives it time to accumulate mana across multiple turns, and green's ramp suite means it realistically attacks for 10+ power by mid-game. In Legacy and Vintage, it's legal but rarely seen — those formats move too fast for a three-mana creature that needs several turns to threaten, and the payoff doesn't justify the opportunity cost against the format's interactive density. Oathbreaker is the one non-Commander 60-card-adjacent format where Omnath, Locus of Mana sees occasional play as the signature spell package, since the format's focus on a single activated ability pairs naturally with green's mana stockpiling.

Cheaper options that do most of the same work
Nothing replicates Omnath, Locus of Mana exactly — the mana-doesn't-empty clause is unique — but Vorinclex, Voice of Hunger fills a related role by doubling your mana production and taxing opponents, which accomplishes a similar "I have more mana than you" game state. If the goal is purely a large green body that rewards mana investment, Managorger Hydra grows on any spell cast rather than mana floating, which is less explosive but harder to blank through interaction.
Price Context
Current price
$8.21 mid tier
At $8.21, Omnath, Locus of Mana sits in the mid tier — affordable enough to include without budget anxiety, but not a bulk pickup. The price reflects its uniqueness: nothing else in the format replicates the persistent mana storage clause, so demand stays steady without requiring a reprint to move.
