What's the point of Abyssal Designator? That's a useless card especially for this kind of deck. Embodiment of Apophis and Tribute Doll should replace Abyssal Designator. You need cards that will help you summon a 7 star monster more effectively.
My first Ultra Rare out of the pack, then when I reset after about 30.... I got another but Prismatic!! That being said I've put about $20 dollars into the game getting the super and ultra rare deal packs.
