Let's see what the rough ratios are for Arcane Wizardry and how it compares: 44 mana sources: 38 lands and Sol Ring, Fellwar Stone, Commander's Sphere, Darksteel Ingot, Unstable Obelisk, and Worn Powerstone 15 sources of card advantage: Inalla, Archmage Ritualist is the ultimate source of card advantage by turning nearly all your Wizards into advantage by copying them (e.g., Apprentice Necromancer), but ignoring her ability, we also have Nin, the Pain Artist, Izzet Chemister, Corpse Augur, Kess, Dissident Mage, Azami, Lady of Scrolls, Mercurial Chemister, Taigam, Sidisi's Hand, Arcanis the Omnipotent, Etherium-Horn Sorcerer, Magus of the Mind, Niv-Mizzet, the Firemind, Opportunity, Curse of Verbosity, and Shadowmage Infiltratorholy crap, so much card advantage
I won't pretend Faerie Mastermind is the equal of either of those powerhouse enchantments, but it's still a great card and if you're not running it, you probably should
If the last card you exile is a modal double-faced card, you may only cast the back face if the resulting spell would also have a lesser converted mana cost than the spell with cascade
Start with smaller trades to establish trust
