Breya's Apprentice

The trick is that it feeds itself. It enters, makes a Thopter, and the first sacrifice cost is paid without touching anything you were saving: the token exists precisely to be eaten by the tap ability. That closes a loop that would otherwise stall a sacrifice outlet on turn three, when spare artifacts might not be lying around. The activated ability consumes fodder whole (the artifact goes to this creature's cost, not to any secondary effect, so a Treasure fed here is a Treasure that never made mana and a Clue that never drew), which reframes what "fuel" means: you are trading finished-with artifacts and expendable tokens for one of two modes. One exiles the top card of your library and lets you play it through your next turn, turning an outlet into an impulsive card-advantage engine. The other pumps a creature +2/+0, converting that same fodder into combat reach when the board wants closing rather than digging. Refill or finish, chosen per activation: that flexibility is where the design earns its slot. The 2/3 body stays deliberately small because the card is not built to attack for the win; it is built to convert an artifact-heavy battlefield into either cards or damage. Named for a four-color artifact commander, it reads as a color-pared distillation of that strategy, handing red a sacrifice outlet that brings its own first meal.
