@@ArcDesMaster It's a little disappointing that you only fulfilled the prompt, and made nothing else on the cards care about the fact that it uses ATK instead of Levels. For example, you could have made the Ritual Monster care about Xyz or Link Monsters because they don't have Levels. As it is, it feels more like you just designed a random Ritual Monster and shoehorned the prompt into it. I accidentally left the use-this-card-in-hand-as-Synchro-Material effect on my card (now removed). Chaos Dark Magician Spellcaster/Ritual/Effect DARK Level 7 ATK 2500 DEF 0 You can Ritual Summon this card with "Chaos Form". Must be Ritual Summoned. Cannot be destroyed by battle, also monsters you control cannot be destroyed by card effects. Once per turn, if you control this card that was Ritual Summoned using "Dark Magician" (Quick Effect): You can shuffle 1 face-up Continuous Spell/Trap you control into the Deck; draw 1 card, then 1 face-up card on the field has its effects negated, also it is banished when it leaves the field. Not too sure how the naming convention would work with this, and it wasn't really feasible making this LIGHT when its name is Dark (or Black) Magician, and that component can't be removed (like White -> Chaos or Chaos MAX) without removing "Dark Magician" from its name. A Ritual Monster that can let itself be Tributed or used as material while it is in the hand.
