Answer 1

dark world lightning is not that good use dark core instead

and lightning vortex is a  good card to.  A card that you can block attacks with and toss cards is Raigeki Break. Snipe hunter is a rely good card AND you toss away cards. All dark world cards is dark so you can get card based on darkness to like

allure of darkness

I don't know if dark world attacks so much but if they do you can ad Mystic Plasma Zone to
