Rulings

 * If you use Counterattack against a Link Attack, you choose only one of the attacking monsters to destroy.
 * Counterattack is compulsory, you must use it if able.
 * Counterattack destroys a card with an ability not an attack, so abilities that activate by attacking do not activate when you use Counterattack.
