Turbo describes decks engineered to execute their primary game plan unusually quickly, often by sacrificing long-term resources for mana, cards, or speed. The term modifies another strategy rather than identifying one specific archetype.
A Turbo Reanimator deck might use rituals and fast mana to revive a creature on the opening turn, while Turbo Depths accelerates the Dark Depths combo. Consistency and resilience are often traded for raw velocity.
