Roaring Slagwurm hits the board as a 7/4 trampler that forces opponents into an awkward choice every combat — tap out to block or watch it through. Seven mana is a real cost, but under Baru, Wurmspeaker it becomes a must-answer threat that also triggers Baru's copy ability, making the price tag easier to justify.

Baru, Wurmspeaker
Baru, Wurmspeaker's ability to create a token copy of each Wurm you cast means Roaring Slagwurm immediately doubles its board presence, and the tap-down ability on the original becomes a political weapon while the token swings free.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| pauper | not legal |
| oathbreaker | legal |
Roaring Slagwurm is legal in Commander, Legacy, Modern, Vintage, and Oathbreaker, but its home is Commander and essentially only Commander. In Legacy and Vintage, seven mana for a vanilla-adjacent creature is unplayable — those formats kill or win before it resolves. Modern has enough efficient threats that a 7/4 with no protection doesn't survive long enough to matter. In Commander, the multiplayer math changes the calculation: the tap-down ability generates real political leverage across three opponents, and Wurm tribal synergies under Baru, Wurmspeaker make it a legitimate include rather than a curiosity.

Price Context
Current price
$0.37 bulk tier
At $0.37, Roaring Slagwurm is deep bulk — it costs less than a sleeve and will stay there given its narrow appeal outside Baru, Wurmspeaker lists. Pick it up without hesitation if Baru is your commander; there's no financial risk at this price point.
