Type: Continuous
Magic
Effect: Select 1 face-up Magic Card
on the field. The controller of the Magic Card must take damage of 500 Life
Points during each of his/her Standby Phases. When the selected card is
destroyed or removed from the field, this card is also destroyed.
Terrible card. Your opponent shouldn't be allowed to get a Continuous Magic Card out for more than a few turns. Use Typhoon instead of this card, its far less situational.You'd be better off just destroying their magic/trap than doing 500 damage a turn.
Another bad card. Do not think that your opponent will leave this card on the field to kill them. M/t removal is way too big and this one is kind of a waste anyway. 500 points is not that much. Start putting in some Typhoons or some Heavy Storms if you find THIS useful.
