Cowl Prowler
Six mana buys a 6/6 Wurm with nothing printed beneath the type line: no evasion, no triggered text, no activated ability, just a large green body and the willingness to stand in front of things. That is the whole transaction. A 6/6 sits above most of what green's contemporaries field on the ground, blocks nearly anything that does not fly or trample, and eats smaller attackers that walk into it without ever asking for a card in return. What it does not do is justify a slot next to creatures that cost the same and also do something, which is most creatures at this rate. The honest read is that this is filler in the oldest sense: a common-rarity beater that gives a green-leaning deck a top-end ground stop, a body that punishes an opponent for not having an answer and contributes nothing when they do. The Wurm tribe is the only flavor hook, and even that is decorative here. As vanilla creatures go the rate is fair, but fair rates on bodies without text age the fastest, because every wave of design after this one hands green a 6/6 (or a 5/5) that also carries an ability. A wall that only walls earns its keep when big green creatures are scarce, and loses it the moment they are not.
