yugioh timaeus dragon card : DRL2-EN001 1st Ed the Knight of Destiny Secret Rare or 1 Spell/Trap that mentions Dark Magician Timaeus the United Magical Dragon

Teach by Example Expansion/Explosion Ral, Storm Conduit Saheeli, Sublime Artificer Thousand-Year Storm Galvanic Iteration Gandalf the Grey Melek, Izzet Paragon Saheeli Rai Protean Raider Najal, the Storm Runner Dack's Duplicate Nivix Guildmage Board Clear Despite sometimes having their experiments blow up in their faces, Izzet mages don't typically set out to make massive, board-clearing explosions

It regularly exceeds the $500 threshold that other ultra rares have not yet surpassed

I wish to avoid any trouble and only for playing

Are there any top notch cards I missed (I realize red and black didn't get much love in this list)
