Should I get Yugioh Spellcaster's Judgement or Zombie World?

So those are my set in stone choices. I want of those two and nothing else but I don't know which one. If I get Spellcaster's Judgement (which is the earlier Spellcaster structure deck) I can put in 1 skilled dark magician and 1 dark magician but if i get Zombie world i have nothing to cards to contribute to that deck. So which one should I go for? Remember I can only buy 1 of them and I just want the better deck too. BUT ALSO KNOW I'M NOT BUYING ANY MORE YUGIOH CARDS AFTER THIS!!!
