Invasion of Kamigawa

Battle — Siege

(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, the 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 a stun counter from it instead.)
