Pay 1000 LP, then target 1 Level 7 or higher Spellcaster-Type monster you control; this turn, only that monster can attack, and it must attack all monsters your opponent controls, once each. The effects of Effect Monsters destroyed by these attacks do not activate and are negated.
Now that I think about it, perhaps we'll get nice rewards too from Yami Marik. Mufasa, you're really short on Gold, aren't you? Well, Yami Marik's event will surely bring us a lot of Golds and Gems though. :)
Dark Paladin could see some use with this card. Yami Yugi used this against Kaiba during Battle City to defeat his Blue Eyes Ultimate Dragon.
