Idk if I'm going to do it now. Yesterday I just took the easy way out and used blue-eyes. I put giganticastle and that rank 8 number thing in my extra deck and those were my rocks... It might be easier for me to do gem knights if Konami hadn't demolished Balance.
All they had to do was this: Balance- "This skill will not activate if your deck contains any cards with "Noble Knight" in their name and text." Problem solved.
