Invasion of Kamigawa

Rules & flavor text

(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 this Siege enters, 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.)
//The pace of Kamigawa's development meant that Jin-Gitaxias's intel was already outdated when the invaders arrived.
