Hidden Cataract card art
Hidden Cataract enters the battlefield and immediately puts a counter on every land you control, turning your mana base into a type-smeared engine that feeds counter-synergy commanders at zero ongoing cost. The one-time price is a single blue mana and a card slot — efficient enough that in the right shell it's an auto-include, and irrelevant outside of it.

Best Commanders

Commanders with the highest synergy

01
Omo, Queen of Vesuva

Omo, Queen of Vesuva

29.2% of decks · synergy 0.27

Omo, Queen of Vesuva spreads counters across permanents to erase type lines and enable cross-type synergies, and Hidden Cataract front-loads that work by dropping a counter on every land at once the moment it resolves.

02
Kellan, the Kid

Kellan, the Kid

27.4% of decks · synergy 0.26

Kellan, the Kid cares about counters on permanents as a resource, and Hidden Cataract delivers a wide counter distribution across the mana base in a single trigger — exactly the kind of efficient setup Kellan decks want to accelerate their engine.

Hidden Cataract is a Commander card through and through — the payoff for flooding your lands with counters only matters when your commander or supporting pieces care about counter types, and that density of synergy lives almost exclusively in 100-card singleton. In competitive 60-card formats like Modern and Pioneer, a sorcery-speed enchantment that does nothing to the board state and doesn't advance a linear gameplan simply doesn't make the cut. Pauper and Legacy are similarly uninterested — neither format has a counter-on-lands archetype that needs this effect. Standard is the one context where Hidden Cataract could see fringe play if the right Omo-adjacent synergies are legal simultaneously, but it's a build-around piece, not a standalone.

Price Context

Current price

$0.17 bulk tier

At $0.17, Hidden Cataract is deep bulk — pick it up without hesitation if Omo, Queen of Vesuva or any counter-stacking commander is on your build list. Bulk rares with narrow synergy profiles rarely climb unless a new commander breaks the effect wide open, so treat it as a cheap enabler, not a spec target.
