The tap symbol in the activation cost is the entire balancing act, and it changes what kind of engine this becomes. A repeatable sacrifice outlet that drains and gains a life per pop would be a dangerous free loop; gating it behind the tap holds it to one activation per turn cycle, so the drain reads as a slow bleed rather than a burst. That single constraint keeps it out of the fling-everything company that fuels combo kills: it will not empty a board in one turn, it will not close a game out of nowhere, it just converts your dying and disposable permanents into an incremental clock. Where it earns its slot is the breadth of its diet. Artifacts and creatures both feed it, so it sits comfortably next to token generators, treasure decks, and anything that leaves expendable bodies or trinkets behind, turning those leftovers into damage on a body opponents cannot ignore forever. The trade of tempo for reach is the whole proposition: you accept the once-per-turn ceiling in exchange for an outlet that also happens to be a 2/2 able to block and attack while it grinds. This is aristocrats plumbing, plain and useful, built for decks that want their sacrifice fodder to keep mattering after it hits the yard.
