Caught in the Crossfire

Board wipes almost never come in halves you can buy separately, and that is what Spree turns this into. The two modes each deal 2 damage, one to a creature type bucket (the outlaws: Assassins, Mercenaries, Pirates, Rogues, and Warlocks) and one to everything outside it, and you pay a mana per mode you take. Pick one and you have a selective sweeper that spares your own half of the board, contingent on how your creatures are typed; pick both and you have a symmetric 2-damage wrath at four mana total. The design puts the partition decision in the caster's hands rather than baking it into the card, which is the reversal that makes it interesting: instead of building a deck to survive a fixed sweeper, you build a board of the right creature types and then choose which side of the line the damage falls on. The catch is that the outlaw split is fixed by the game's tribal definitions, not by your choice, so the card rewards knowing exactly what everyone at the table is running rather than what you wish they were. As a two-toughness sweeper it is a soft answer to go-wide aggression and a dead card against anything larger, but the flexible cost means you rarely overpay: you spend only for the half of the board you actually need cleared.
