Meticulous Excavation

A repeatable bounce engine that costs one white mana to deploy and then never leaves, which is the whole difference between it and the parade of one-shot flicker spells white has always had. The self-bounce clause is the tell: this was built to reset your own enters-the-battlefield triggers on demand, turning any single value creature into a wellspring you tap for three mana. The activation being locked to your own turn keeps it from doubling as a combat-phase escape hatch on the opponent's swing, which is the restriction that separates it from an instant-speed permanent tuck. The unearth rider is the genuinely clever part: unearth creatures are designed to die and stay dead, so ordinarily a bounce spell can't rescue them at all. Here the ability detours around that, exiling the unearthing permanent first and then returning it to hand as a fresh card, laundering a creature that was supposed to be spent back into a full recastable copy. That interaction reads as narrow, but it is really a statement of intent: this is an artifact-adjacent value piece that cares about a specific graveyard-mechanic ecosystem, and its power scales entirely with how many triggers and how much unearth you have to feed it. On its own it recurs a single dork every three mana; wrapped in the right density of entry effects it becomes a slow, grinding advantage machine.
