Assemble the Rank and Vile

A card type that never enters your deck and never gets cast: it begins the game face down in the command zone, costs nothing because casting is not how it works, and earns its power entirely from information you keep hidden. The hidden agenda is the whole engine. Before anyone has drawn a card, you secretly commit to a name, then sit on that choice until the moment it pays off. The effect keys off the name rather than a specific copy, so every creature you control sharing that name becomes a death-triggered zombie factory once you flip the conspiracy face up. The bet is placed in the dark: you are wagering on a card you expect to draw multiples of, or one already central to your plan, since the trigger only ever applies to your own creatures. The payment on each death keeps the value gated rather than free, so the conspiracy rewards a board built to die into it rather than a single lucky trade. What gives the design its teeth is the gap between reveal and threat: an unflipped agenda is pure bluff, and the suggestion that you might have named the creature about to block can be worth more across a table than the tokens it would have made. Naming, waiting, and reading the room are the actual gameplay here, not the rate of the bodies you eventually assemble.
