Summoning Station

Most token factories are throttled by their own tap symbol: one body per turn, the activation doing the work of a clock. The second line here is a deliberate release valve on that clock, and it points at a different resource entirely. The untap fires whenever an artifact dies on the battlefield, so the Pinchers stop arriving on a per-turn schedule and start arriving on a per-death one: feed enough metal through a graveyard and the drip becomes a flood. The wrinkle is that the tokens it makes are colorless creatures, not artifacts, so sacrificing them back into the engine does nothing by itself; you need a separate supply of expendable artifacts to die, plus an outlet that eats them, before the untaps begin compounding. That two-part requirement is the gating. Left alone it is a slow seven-mana producer; assemble the artifact-death machinery around it and each sacrifice refunds an activation, the loop sustaining itself for as long as the fodder holds. What makes the design notable is the lens it puts on a permanent leaving play: an early piece to treat artifact death as fuel rather than loss, an idea that has recurred steadily since in cards that profit from their own things dying. The colorless Pinchers were built to live among artifacts and reward stuffing the board with cheap, breakable parts. The tap-for-a-2/2 reads modest; the ceiling sits much higher, behind a real assembly cost.
