Chitterspitter

A green artifact that runs a Squirrel tribe from three angles at once, and the interesting part is how the pieces feed each other. The activated ability is the floor: pay a green mana and tap to manufacture a 1/1, a repeatable sink that ensures the board never runs empty and always has fodder on hand. That fodder is the fuel for the upkeep trigger, where you may eat a token to bank an acorn counter on the artifact itself. And the static anthem reads every acorn counter as a permanent +1/+1 for the whole Squirrel army. Chain those together and the card describes a loop: generate width, convert width into height, regenerate width, convert again. The counters are what make the trade lopsided. Because they sit on the artifact rather than on the creatures, a board wipe erases the token army but leaves the accumulated buff intact, so the next generation of Squirrels arrives pre-pumped. Left alone across a few turns, the anthem compounds faster than the token rate that fuels it. The green mana behind both the casting cost and the activation keep this anchored to a Squirrel shell rather than splashed as a colorless value piece; it wants to be a tribe's centerpiece, a lord that also builds its own subjects, and the longer it survives untouched the further its ceiling drifts from anything a fair board can profitably answer.
