This is a 50 card deck with four engines: Endymion (for spell counters), Spellbook ( for draw power and deck thinning), Mythical Beasts (more spell counters), and Pendulum Magicians (for easy swarming and material).
Here’s the overall strategy with this deck: you first need a way to get spell counters on board, as this will lead you to a desirable outcome whether that will be OTK or 6-8 negates on turn one.
If you are wondering the best way to get to those boards, it really just depends on the hand you get. Sometimes it good enough, sometimes it’s barely serviceable, and a lot of times it gives you way more to go off of.
Anyways, Servant is gonna be your primary play maker, SS one of your negates (Jackal or Endymion), link them off into Crowley or Day-Breaker, again, depending on the hand. The Spellbooks are gonna help you a lot with thinning the deck to get to your negates or materials, as well as the Mythical Beasts being a way to get more spell counters on board.
Crowley into Secrets or Spellbook Magician of Prophecy, then go into Knowledge for draw power. Your next move is gonna have to be a way to link off without the need of a pendulum summon. If you have Pot of Desires, Pendulum Call, Duelist Alliance, Spell Power Mastery, Or Allure of Darkness, or any combination of them, go ahead and do your searches and draws to get Magister of Endymion, activate Magister, get Servant, then link off into Selene, use her effect to get Spellbook Magician, then link them off into Apollousa with 2-3 negates. Now is the time to pendulum summon. You can easily get 6-8 negates on board turn one, or manage to get 8000+ damage on board going second if you summon Avramax.
