Invasion of Kamigawa

(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, then cast it transformed.) When Invasion of Kamigawa enters the battlefield, tap target artifact or creature an opponent controls and put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.) // Rooftop Saboteurs Flying Whenever Rooftop Saboteurs deals combat damage to a player or battle, draw a card.

The pace of Kamigawa's development meant that Jin-Gitaxias's intel was already oudated when the invaders arrived.
