Stronghold Gambit

A red sorcery that puts a creature onto the battlefield is already strange; one that asks both players to participate in a simultaneous reveal is stranger still. The mechanic is a hidden-information game run in reverse: each player secretly commits a card from hand, everyone flips at once, and the owner of each lowest-mana-value creature revealed gets to put it into play for free. The crucial wrinkle is that the comparison only counts creature cards, so the way to weaponize this is not to play small. If your opponent reveals a noncreature (or has no creature to reveal at all), your revealed threat is the lowest by default and walks onto the battlefield, however expensive it is. The card rewards the player who knows the opponent's hand cannot undercut them: you cast it when their grip is thin, then flip your fattest haymaker and watch nothing contest it. The danger runs the other way too, since an opponent holding a cheap body can reveal it and steal the effect for themselves, dragging a creature of their own into play instead of yours. That bluffing layer (do they have a creature; can they go lower than mine; is it worth committing my best card to the reveal) gives the spell the texture of a poker hand rather than a tutor. It is a symmetrical design that reads as fair on the page while quietly handing the advantage to whoever reads the table best.
