Tide of War

Enchantment, 4RR (6)
Whenever one or more creatures blocks, flip a coin. If you win the flip, each blocking creature is sacrificed by its controller. Otherwise, each blocked creature is sacrificed by its controller.¹
Illus. Wayne Reynolds

Gatherer Card Rulings [Nov 2009]

• 12/1/2004: Tide of War's ability triggers only once each combat and only if at least one blocker is declared. The effect does nothing to unblocked attacking creatures.
• 12/1/2004: Tide of War's controller always flips the coin. This means that you want to win the flip when you're attacking but lose the flip when you're defending.
• 12/1/2004: Even if the blockers are sacrificed, any attackers that were blocked are still considered blocked.
• 5/1/2007: In the 2HG format, all the attacking and blocking creatures are affected, not just the ones controll
