Oxygen Destroyer

{8}, {u}, {b}, {w}, {t}: Destroy any card on the field, no matter what type of card it is.
"If the Oxygen Destroyer is used even once,
politicians from around the world will see it. Of
course, they'll want to use it as a weapon. Bombs
versus bombs, missiles versus missiles, and
now a new superweapon to throw upon us all!"
