Card Rulings:Boss Rush


 * You cannot activate "Boss Rush" if you have already Normal Summoned or Set a monster this turn.


 * "Boss Rush" must be face-up on the field when the "B.E.S." or "Big Core" monster is destroyed for you to use its effect. If the monster is destroyed, and then afterwards you activate "Boss Rush", you do not get to Special Summon for that monster's destruction.


 * You can use the effect of "Boss Rush" during your opponent's turn, as long as it was already face-up on the field and an appropriate monster was destroyed during that turn.


 * If more than 1 appropriate monster is destroyed during the turn, you can still only Special Summon 1 monster during the End Phase for "Boss Rush". If you have 2 copies of "Boss Rush" on the field, then you can Special Summon 1 monster for each copy of "Boss Rush".


 * Activating the effect of "Boss Rush" during an End Phase is an effect that can be chained to.
