Twilight Diviner

The trigger clause everyone skips to is the one that gates the whole engine: not just any creature entering, but a creature that entered or was cast from a graveyard. That is a narrow window, and it is the point. The surveil 2 on the front end is not incidental value; it is the setup, feeding the graveyard the copy-fodder the second ability wants to reanimate or flash back. What results is a self-priming loop where the same body fills the yard and then rewards you for cashing it back in, copying whatever crawls out. The once-per-turn clamp keeps the loop from spiraling: you get one token per turn no matter how many graveyard creatures pile in, which forces you to earn maximum value from that single copy rather than to chain a combo that resolves itself. It sits in a long line of black recursion payoffs that care about how a creature arrived rather than merely that it arrived, a design lever that lets a modest 3/3 anchor a graveyard deck without being an outright engine on its own. The stat line is deliberately unremarkable; the value lives entirely in the sequencing you build around it, turning each reanimation into a two-for-one and each self-mill into ammunition for the next.
