Demonlord Belzenlok card art
Demonlord Belzenlok lands as a 6/6 flying trampler and immediately refills your hand — or drains your life total if your deck skews high on CMC. The self-damage is real enough that shells like Be'lakor, the Dark Master pair it with Selective Memory to scrub the library clean of non-demons before it triggers, turning the drawback into a clean two-card combo.

Commanders with the highest synergy

Be'lakor, the Dark Master

Be'lakor, the Dark Master

19.2% of decks · synergy 0.18

Be'lakor, the Dark Master draws a card off every demon that enters the battlefield, so Demonlord Belzenlok's cascade of enters-the-battlefield demons from its own trigger becomes raw card advantage on top of card advantage — and the Selective Memory line makes Belzenlok a reliable one-card win condition rather than a liability.

03
Kaalia of the Vast

Kaalia of the Vast

15.0% of decks · synergy 0.13

Kaalia of the Vast cheats Demonlord Belzenlok into play attacking, which means the trigger fires without ever paying six mana — you get the 6/6, the card dump, and the combat damage all at once.

04

Liliana, Heretical Healer

12.5% of decks · synergy 0.12

Liliana, Heretical Healer flips off any creature dying, and Demonlord Belzenlok is a high-value demon that Liliana, Heretical Healer can reanimate or sacrifice to her own abilities, feeding both the graveyard and the devotion to black that the deck wants.

05
Varragoth, Bloodsky Sire

Varragoth, Bloodsky Sire

7.9% of decks · synergy 0.07

Varragoth, Bloodsky Sire tutors Demonlord Belzenlok to the top of the library on a boast trigger, letting you set up the exact draw you need and chain into the cascade effect on your next main phase.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Commander is where Demonlord Belzenlok actually lives — the singleton format rewards its high ceiling, demon tribal decks want a top-end threat with a built-in draw engine, and the life-loss drawback is manageable when you start at 40. In Legacy and Vintage it's legal but irrelevant; six mana for a creature that might dome you is nowhere near competitive in those formats. Modern and Pioneer are theoretically accessible but the same problem applies — too slow, too fragile, and too reliant on a library full of low-CMC spells to avoid punishing yourself. Oathbreaker is the sleeper slot where Demonlord Belzenlok could serve as a signature-spell target or top-end finisher in a 20-life format, though the self-damage becomes sharper there.

Price Context

Current price

$0.39 bulk tier

At $0.39, Demonlord Belzenlok is bulk, and that price reflects its narrow application rather than its ceiling — it's a powerful card in the right shell, not a staple with broad demand. Don't expect the price to move unless a new demon commander pushes the archetype into a wider spotlight.
