Adriana's Valor

The hidden-agenda mechanic builds a whole layer of gameplay out of nothing on the battlefield: you start with this in the command zone, secretly name a card, and the table watches for the reveal. What's interesting is how little the named-creature payoff actually does relative to the bluff that precedes it. The combat reward (paying white to make an attacker of the chosen name indestructible) is a slow, conditional protection that only triggers on attack and only on the one name you committed to before the game began. The real design weight sits in the choosing and the concealment. Naming a creature is a prediction about your own deck and a tell-management exercise: reveal too early and opponents play around the protection; sit on it too long and you may never draw the named card at all. This sort of conspiracy turns deckbuilding into a closed-room information game, where the value comes from the commitment you make sight unseen and the timing of when you let the others in on it. The indestructible grant is the lever; the secret is the machine.
