{T}: Switch the blocking creatures of two target attacking creatures. Activate this ability only during the declare blockers step.¹
Illus. Richard Thomas

Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Does not undo any abilities which triggered due to the declaration of blockers. A creature which is switched away still has any triggered abilities resolve on it.
• 10/4/2004: The new blocker does not trigger any abilities which trigger on creatures becoming blockers, because the creatures were already blockers and the simple change of who is blocking does not trigger such abilities.
