Rollick of Abandon

A symmetric toughness-stripping wrath that doesn't read like one. The +2/-2 swing kills nothing larger than a two-toughness creature outright, so the card's real job is to clear a board of weenies and tokens while inflating whatever you have left into a lethal swing. That asymmetry hides inside a symmetric effect: it punishes go-wide decks built on small bodies and rewards the player whose threats survive the toughness hit. What makes the card a curiosity is that the mechanism is borrowed. Toughness reduction (-X/-X) is black's signature, the way Drown in Sorrow or any number of black sweepers do their work; red almost always burns the board down with damage, as Pyroclasm does. This reaches into the neighboring color's toolkit and bolts a red buff onto it, and that buff is why it isn't a clean kill spell: rather than merely shrinking the field, it hands your surviving attackers two extra power apiece, folding answer and finisher into one card. The catch is the one every symmetric effect carries: your opponent's survivors get the buff too, so the card wants a battlefield you've already tilted in your favor, not a coin flip. At five mana and sorcery speed, it is a deliberate turn rather than a reactive trick, which suits its function as a planned tempo reset more than an emergency button.
