Tide of War rulings:
2004-12-01: 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.
2004-12-01: 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.
2004-12-01: Even if the blockers are sacrificed, any attackers that were blocked are still considered blocked.
