Most of these cards will premier in AGOV (Age of Overlord), like the "Diabellestarr", new "Horus" cards, as well as Stellar Nemesis T-PHON - Doomsday Star, the new Anti-Zeus card. Cards like Imsety, Glory of Horus, Pharaonic Sarcophagus, Diabellestarr the Dark Witch, snd Magicians' Souls all send cards from your hand to gain you advantage in one way or another, like how Diabellestarr summons itself and gives you access to "The Sinister Spoils" Spell/Traps, or how Souls sends Spells or Traps to draw you cards. However, you can easily refill you hand with cards like Coach King Giantrainer, which can draw you 3 cards! or Duamutef, Blessing of Horus which can draw you up to 5!
Souls can send either Illusion of Chaos or Diabellestarr from your deck to summon itself, and you can potentially reborn Diabellestarr later with a card like Selene, Queen of the Master Magicians, which you can make with Imsety, Souls, Dharc the Dark Charmer, Gloomy, or even another Diabellestar. Overall, this deck is very consistent, and extremely flexible and fun, enjoy.
