Spined Wurm

For years this was the yardstick green's commons were measured against: a 5/4 for five with an empty text box, no keyword, no trigger, nothing to read. That blankness is the point. It exists to establish what vanilla green costs in a given era, the baseline rate against which everything carrying a keyword or a battlefield trigger gets priced. A 4/4 trample creature, a 5/3 with reach: each gets evaluated against this reference body sitting in the back of the mind. The 5/4 split does quiet work: it dies to most four-toughness-relevant burn and trades up against the 4/4s and 5/3s that share its slot, but its five power folds a lot of midrange blockers and clocks an opponent in four hits. Green has spent the decades since printing strictly better versions of this shape, creatures that match or beat the body and staple something useful on top, which is exactly the trajectory you would expect: the vanilla rate is the floor power creep climbs away from. The Wurm itself does nothing clever and was never meant to. It is the honest measuring stick, and the reason so many later green beaters read as upgrades is that this is what they are upgrading from.
