Brago's Favor

Hidden agenda put information warfare on the table before a single spell was cast, and this is its most quietly aggressive expression: a permanent, deck-spanning discount that exists outside the game's normal economy entirely. The chosen name is locked in before any card is drawn, which makes the discount a planning decision rather than a reactive one. You commit to a name you expect to cast repeatedly (a marquee spell you built around, or a name you happen to know you have several copies of), and the reduction applies at the moment of casting, every time, whether or not the spell ever resolves. That distinction matters: the rebate is banked when you put the spell on the stack, so a countered cast still spent fewer mana getting there. The face-down clause is the leverage: opponents see a conspiracy in your command zone and have to reckon with the possibility that whatever you cast next is coming a mana cheaper, without knowing which card carries the rebate until you choose to reveal. That ambiguity can be worth as much as the mana itself, shaping how the table sequences removal and counters around a discount that may not even be live yet. Unlike a card in the deck, it costs nothing to include and occupies no slot in play; it rides along from turn zero, rewarding a focused list over a toolbox one, since the value scales directly with how often the named spell shows up.
