Bubbling Muck doubles your Swamp output for a single black mana — the same effect as High Tide, but for black — and in a mono-black shell that can already recur instants, that's a one-card engine. Toshiro Umezawa can flash it back from the graveyard after a creature dies, and Magus of the Candelabra turns the floating mana into a repeatable engine on the same turn.
Best Commanders
Commanders with the highest synergy
Toshiro Umezawa
Toshiro Umezawa triggers on opponent creature deaths, letting him flashback Bubbling Muck from the graveyard — meaning a single combat step can refund and redeploy the full mana burst.
Valgavoth, Terror Eater
Valgavoth, Terror Eater wants to cast a massive commander on curve and then keep paying life-loss triggers; Bubbling Muck provides the sudden mana spike to land Valgavoth ahead of schedule or recast it after removal.
Phage the Untouchable
Phage the Untouchable costs seven mana and punishes any stumble in reaching that number; Bubbling Muck can push a mid-game board of Swamps over the threshold in one shot, letting Phage land before opponents are ready.
Acererak the Archlich
Acererak the Archlich wants to enter, get dungeoned back, and recast repeatedly in one turn; Bubbling Muck generates the burst mana needed to pay Acererak's cost multiple times in a single main phase.
Gix, Yawgmoth Praetor
Gix, Yawgmoth Praetor's card-draw ability scales with how many creatures deal combat damage, and Bubbling Muck lets him dump the resulting hand back onto the board in the same turn he draws it.

Commander is where Bubbling Muck lives — mono-black decks routinely run 35-plus Swamps, and a resolved Muck can add ten or more mana in the late game, enabling explosive same-turn plays that High Tide decks in blue have long exploited. In Legacy and Vintage it's technically legal but sees essentially no play; storm and fast-mana shells there have more efficient lines, and Bubbling Muck's sorcery speed cuts it out of the permission-heavy games those formats produce. Pauper is the sleeper home: mono-black control builds with enough basic Swamps can use it as a finisher enabler, and at common it's easy to acquire.

Current price
$3.26 cheap tier
At $3.26, Bubbling Muck sits in the cheap tier but punches above that price in mono-black Commander decks, where it's a functional staple with no direct substitute. Demand is narrow enough that the price has stayed flat — it's not a card that spikes, but it's also not going to get cheaper.
