The key to this and my pal AoJ Unknown Crusher is playing them without brick transplants. Make room for staples in your deck, and things to keep your AoJs on the field.
Unkown Crusher is even worse. D.D. Warrior does exactly the same thing but you don't need DNA Transplant. And Core Destroyer needs to battle to activate its effect.
That strategy might sound interesting on paper but it will NEVER be a top tier deck.
D.D Warrior isn't better or even equal to Crusher. He always necessarily banishes himself with the monster. As long as Crusher is properly protected by equips/backrow, he can keep removing light monsters without any cost.
