Case of the Shifting Visage
The clever part is how the two abilities feed the same clock. The upkeep surveil is not just card selection; it is the meter that fills the graveyard toward the solve condition of fifteen cards. So the enchantment does its own setup work: every turn it either digs toward a payoff or discards fuel into the yard that pushes the case closer to solving. Fifteen is a high bar for a graveyard, which tells you what kind of deck this wants: one already leaning on mill, self-discard, or heavy cantripping, where the pile fills on its own and the surveil is a bonus rather than the whole plan. Once solved, the reward is a spell-copy engine keyed to nonlegendary creatures, which is a deliberate fence: the copies are tokens, and the legendary exclusion keeps you from doubling your best singleton threats and folding to the legend rule anyway. The intended targets are the workhorses, the value creatures and army-in-a-can bodies, where a second copy compounds an enters-the-battlefield trigger or simply doubles a board. What makes the design coherent is that the same graveyard-matters shell that turns on the solve is exactly the shell that wants a creature-heavy curve to copy; the card asks you to build one engine, not two, and the surveil is the thread stitching the setup half to the payoff half.
