Hired Heist

This one starts the game rather than getting cast: it sits secretly in the command zone from the opening, and it asks you to commit a creature name blind, sight unseen, before the board exists. Hidden agenda is doing something no drafted spell can, letting you lock in that name in advance and then pick the exact moment to flip it face up once the table has confirmed your read. The trigger reads narrowly by design, keyed to a creature you control with the chosen name, so the honest play is to name something you expect to be swinging on your own side, then turn each connection into cards. That inward orientation is the twist on the espionage flavor: the opponent's roster only matters if you steal or clone one of their creatures under your control. The reward is gated twice. The named body has to land combat damage on a player, and then you spend an additional blue to draw. That double lock is what stops a zero-cost engine from running away with the game: the payoff is tied to repeated successful attacks, not a single hit, so the conspiracy is worth exactly as much as your confidence that one particular creature keeps carrying your damage. The whole decision lives at the prediction stage, where you are wagering on which body ends up doing the work.
