Siege Wurm lands as a 5/5 trampler with convoke, meaning a board of creatures can pay most of its seven-mana cost. Outside of dedicated Wurm synergy led by Baru, Wurmspeaker, that's a steep ask for a vanilla-statted body that trades with anything above the bulk threshold.

Baru, Wurmspeaker
Baru, Wurmspeaker triggers off every Wurm entering the battlefield, and Siege Wurm's convoke clause means a wide board can cheat it into play early — exactly the kind of redundant, on-tribe body Baru wants to keep the engine churning.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

In Commander, Siege Wurm is a Baru, Wurmspeaker inclusion first and a general green-ramp payoff never — a 5/5 trample for seven isn't where you want to land in a 40-life format with faster threats available. Pauper is the only format where it earns real consideration, since convoke synergizes with token-wide commons and the power floor of legal creatures is low enough that 5/5 trample actually closes games. In Legacy, Modern, and Pioneer, Siege Wurm doesn't register — those formats kill or win before turn five, and convoke hasn't historically enabled competitive ramp at this mana value.

Price Context
Current price
$0.10 bulk tier
At $0.10, Siege Wurm sits firmly in bulk territory and is unlikely to leave it — demand is narrow enough that even a Baru, Wurmspeaker spike wouldn't meaningfully move the price. Pick it up freely; there's no financial case to think harder about it than that.
