Molten-Tail Masticore

The Masticore template was always a study in self-punishment: a colorless beatstick that taxes its own controller every upkeep, demanding a card from your hand or it dies. This one keeps that discount-paying upkeep clause but bends the whole machine toward the graveyard. A discarded creature each turn is not pure cost; it is fuel, because the firing ability exiles a creature out of your graveyard to throw four damage anywhere. So the upkeep tax that bleeds most Masticores instead stocks the resource this one wants to spend. That feedback loop is the design idea: discard to survive, then exile what you discarded (or anything else that died) to burn a face or a blocker, and regenerate the body to weather what comes back. The repeatable four-damage shot makes it a slow but resilient removal engine, an artifact's claim on inevitability without committing to any one color. The catch is rate. The activated ability is back-loaded enough that it never threatens to run away with a game on its own; you pay, and pay again, to keep it relevant. What it offers is durability through regeneration and a damage outlet that ignores combat, all priced so it asks for a steady stream of resources rather than a single big turn. A grindy, attrition-minded creature in a mechanic better known for trading hand cards away just to keep swinging.
