Tarrian's Soulcleaver

The cheap printing cost and the heavier equip cost pull in opposite directions: the Equipment lands almost for free, but arming it demands a real commitment of a creature and the mana to attach it, so the snowball never starts until you invest. That lag is deliberate; it stops the growth from arriving unpaid. What separates this from ordinary anthem-on-a-stick gear is the breadth of the trigger: it doesn't care who owned the dying permanent or how it died, which quietly rewards the sacrifice-fueled and grind-heavy strategies that treat their own board as fuel. Every token traded away, every blocker eaten, every artifact cracked feeds the equipped creature a counter. Vigilance is the connective tissue that makes those counters count, letting the growing threat swing without abandoning the board that keeps generating its growth in the first place. Legendary status on such a cheap Equipment reads less like a power check and more like a flavor anchor, since nothing about the numbers demands the restriction. This is the counter-accruing Equipment built for attrition rather than voltron: it wants a wide, expendable battlefield around it, and it turns the natural churn of a grindy game into a single, escalating clock.
