Psychotic Haze

Symmetrical one-damage sweepers live or die on how cheaply you can fire them, and the madness cost is the second price tag that justifies playing this one at all. At its full four-mana cost it is a modest board-clipper: it picks off mana dorks, x/1 tokens, and the occasional racing aggressor while chipping both players for one. The design comes alive when the card is discarded rather than held, because madness lets it slip into exile and return for far less, converting the downside of a forced hand-dump into a reactive payoff. That is the structural trick the mechanic pulls across this era of black: a discard outlet (anything that loots, rummages, or makes you pitch) becomes a way to deploy the card at a discount instead of a cost. The spell is natively an instant either way, so it already catches creatures mid-combat or finishes a tapped-out opponent regardless of which cost you pay; what madness changes is the rate, not the timing. The hit to your own life total and your own small creatures is the honest tax on a symmetrical effect, but the damage is low enough that an attrition deck built to discard freely usually comes out ahead on the exchange. It reads as a filler sweeper until you notice it would rather be discarded than held in the hand.
