Card Rulings:Zagan


 * Zagan's effect to negate other monster effects ONLY activates during the Battle Phase when it attacks or is attacked, and lasts only for that Battle Phase.
 * The effect of Zagan that reduces the DEF of the Defense Position monster's DEF by half is compulsory and doesn't target. It affects the current DEF, not the original DEF.
 * Zagan's piercing effect occurs after reduction of DEF has been applied, and uses the reduced DEF for damage calculation.
 * The DEF of the attacked monster does not return to normal if the monster remains on the field (monsters not destroyed by battle, monsters with higher halved DEF than Zagan's ATK)
 * If Zagan attacks a Defense Position monster that has already had its DEF halved by a previous attack from Zagan, the DEF is halved again.
 * If Zagan was Special Summoned successfully in the method described in its card text, it can be Special Summoned by a different effect later.
