Overall, Dragon-type cards are a balancing nightmare that seem poised to dominate the game's meta for years to come
The combination of Doomking Balerdoch and Zombie World pretty much provides you with a negate that you can use once per chain as all monsters on the field are turned into Zombie Monsters with the effect of Zombie World , this means whenever your opponent activates a Monster Effect, you can use Doomking Balerdoch to negate said Effect
