Mine Worker

The joke is older than most players remember: a set of three Assembly-Workers, each named for a piece of the same machine, that do something more together than apart. This one carries the tap-for-life half of that gag, tripling its output only when Power Plant Worker and Tower Worker are on the battlefield alongside it. The reward is deliberately trivial (one life becomes three), which tells you the payoff was never the point. The point is the assembly itself: a puzzle of three specific creatures by name, a Rube Goldberg contraption whose punchline is that you bothered to build it at all. That lineage of "collect the matching parts for a modest bonus" traces back to the earliest attempts at charming, low-stakes tribal-adjacent design, where the flavor of the mechanism outweighed the numbers on it. On its own it is a 2/1 that gains a life when it taps, which is to say it does almost nothing worth a card slot. Assembled, it still does very little. What it represents is a designer's willingness to spend a common on a callback: a wink to anyone who recognizes the three-worker gearbox and wants to reconstruct it for the sheer completionist pleasure of the click.
