Bellowing Tanglewurm card art
Bellowing Tanglewurm gives every green creature you control intimidate the moment it enters, which in a mono-green deck effectively reads as unblockable for your whole board. Five mana for a 4/4 that blankets your team is strong enough that Baru, Wurmspeaker lists include it at nearly 89% — it's a finisher disguised as a creature.

Commanders with the highest synergy

01
Baru, Wurmspeaker

Baru, Wurmspeaker

88.7% of decks · synergy 0.81

Baru, Wurmspeaker builds around large green creatures, and Bellowing Tanglewurm turns every wurm token and fatty into a threat that can only be chump-blocked by other green creatures — which opponents rarely run enough of.

02
Goreclaw, Terror of Qal Sisma

Goreclaw, Terror of Qal Sisma

36.1% of decks · synergy 0.28

Goreclaw, Terror of Qal Sisma reduces Bellowing Tanglewurm's cost and gives your big creatures trample, so the intimidate from Bellowing Tanglewurm handles the creatures that would otherwise chump-block while trample handles the rest.

03
Fynn, the Fangbearer

Fynn, the Fangbearer

34.3% of decks · synergy 0.27

Fynn, the Fangbearer kills with poison counters on combat damage, so Bellowing Tanglewurm's board-wide intimidate is exactly the enabler it needs — deathtouch creatures that can't be blocked deal their poison freely.

04
Thrun, Breaker of Silence

Thrun, Breaker of Silence

34.2% of decks · synergy 0.26

Thrun, Breaker of Silence already dodges interaction through hexproof and can't be blocked by spells, and Bellowing Tanglewurm layers intimidate on top so the rest of your board punches through alongside it.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander
legacy
modern
pioneer
standard
vintage
pauper
oathbreaker

Bellowing Tanglewurm is legal in Commander, Legacy, Modern, Vintage, and Oathbreaker, but it only sees meaningful play in Commander. In Legacy and Vintage the five-mana cost and symmetry-dependent effect can't compete with the format's density of non-green threats and efficient answers. Modern's aggressive clock makes a five-mana 4/4 without immediate protection too slow outside of fringe green stompy lists. Commander is where Bellowing Tanglewurm actually lives — multiplayer boards are wide, opponents regularly run few or no green creatures, and a single card that makes your whole team pseudo-unblockable at the cost of one spell slot is exactly the kind of overperformer green finisher decks want.

Price Context

Current price

$0.80 bulk tier

At $0.80, Bellowing Tanglewurm sits firmly in bulk territory despite its near-universal inclusion in Baru, Wurmspeaker lists. That price is stable — it's a casual staple with a narrow home, so demand is steady but not the kind that drives spikes.
