# Battle of Wits Battle of Wits represents a unique design space in Magic: the Gathering—a card that fundamentally changes how you build your deck. Rather than following traditional mana curves and synergies, this rare forces you to construct a 250-card singleton deck, an extreme constraint that appeals to brewers and format innovators. Collectors appreciate it as a conversation piece and a window into Magic's experimental design philosophy. The Ninth Edition printing is straightforward, available only in nonfoil, making it accessible to players seeking the effect without hunting variants. It remains relevant in casual formats where deck-building freedom matters more than competitive optimization.
