Your first statement confuses me. All weapons do is give you an extra attack in exchange for a weakened defence. It's basically a break-even that increases tempo, I don't see how the size of the other cards on my field is relevant to that.

As for the Magic World... the problems with size 1 rush is that while it can easily establish a field, it has trouble maintaining that field against board wipes or flank attacks. Replacing Devil Advantage and Devil Fever for monsters would make it slightly easier to form a starting field, but as I said that's rarely an issue for this deck. Sustainability is a much bigger problem in this deck, and that's where Advantage and Fever shine. As for Destruction... item removal is Kryptonite to Danger and Magic world. In the current game state I would never run a deck without it.
