Is Murkfiend Liege good in Commander?

Murkfiend Liege in Commander — Combos, Decks & Price

Murkfiend Liege pumps every green and blue creature you control and untaps your whole board every upkeep — the stat boost alone justifies the slot, and the untap effect turns any tap-based engine into a recurring threat. At four mana in a two-color identity, the cost is fair for what is effectively a repeating mass-untap stapled to a lord.

Best Commanders

Commanders with the highest synergy

01

Alaundo the Seer

66.3% of decks · synergy 0.52

Alaundo the Seer taps to cast spells for free, so Murkfiend Liege's end-of-turn untap effectively doubles his output every rotation around the table — it's one of the cleanest synergies in the deck.

02

Kumena, Tyrant of Orazca

63.2% of decks · synergy 0.49

Kumena, Tyrant of Orazca runs on tapping Merfolk to draw cards, grant evasion, and place counters, and Murkfiend Liege resets the entire team each upkeep so Kumena can fire every one of those abilities again the following turn.

03

Volo, Guide to Monsters

56.7% of decks · synergy 0.43

Volo, Guide to Monsters copies every nonlegendary creature spell with a new creature type, and Murkfiend Liege pumps the resulting flood of bodies while untapping any tap-activated creatures in the mix.

04

The Master, Transcendent

36.2% of decks · synergy 0.35

The Master, Transcendent exiles cards and creates Dalek tokens by tapping, making Murkfiend Liege's untap trigger a direct extension of his token production each turn cycle.

05

Grolnok, the Omnivore

42.3% of decks · synergy 0.28

Grolnok, the Omnivore incentivizes attacking with Frogs and generating croak counters, and Murkfiend Liege's consistent +1/+1 boost makes that combat math meaningfully more threatening while the untap keeps utility Frogs ready to activate.

Format Analysis

Where it lives, where it can’t

Format	Verdict

pioneer	not legal
standard	not legal
vintage	legal
pauper	not legal
oathbreaker	legal

Commander is where Murkfiend Liege does its best work — the singleton format rewards broad, repeating effects, and a mass untap on an aggressive clock punishes any table that doesn't immediately answer it. In Legacy and Vintage it's technically legal but never played; the formats are too fast and too hostile to a four-mana creature that doesn't impact the board the turn it enters. Oathbreaker is the one non-Commander 60-card variant where Murkfiend Liege sees occasional fringe play in Simic tap-matters builds, though the compressed game length limits how many untap triggers you realistically collect.

Price Context

Current price

$2.31 cheap tier

At $2.31, Murkfiend Liege sits firmly in the cheap tier — high demand from Merfolk, Frog, and tap-synergy Commander builds keeps it from bottoming out further, and a card doing this much work for under three dollars is straightforward value. Expect the price to stay in this range as long as Alaundo the Seer remains a popular commander.
