Mono Air Magician

This build grew out of an earlier three element version that leaned on Water and Fire bombs cast through Mephistopheles for free. That version worked, but it carried real threshold risk and a thin early game. This list simplifies the whole plan around a single element. Every site produces Air, nothing sits dead waiting on a color you never drew, and the mana base is dramatically more consistent as a result.

Mephistopheles is still the engine, not the whole plan. Once he lands, he summons an Evil ally from your hand for free every turn, and several of your best cards, including Doom of Dilmun, Stitched Abomination, and Nightmare, are happy to sit in hand waiting on him. But this version does not need him to function. Apprentice Wizard, Stygian Archers, Bane of Aventis, and Keening Banshee are all real, castable plays on curve with nothing exotic required, so the deck has a game plan whether or not Mephistopheles ever shows up.

Ramp is doing real work here. Amethyst Core, Key to the City, and Philosopher's Stone all add mana or reduce cost every turn once they land, while Mix Aer and Four Waters of Paradise let you cheat a bigger spell into an earlier turn than it has any business coming down. Card draw is spread across Clairvoyant, both Wizards, Browse, Dream Quest, and Black Mass, so a blank early hand is rare and a late game top deck usually still finds something useful.

The Collection, reached through Toolbox and a single Silver Bullet for Exceptional access, is built to cover what the main sixty struggles to answer on its own. Disenchant handles artifacts and auras, Murder of Crows clears wards through its damage trigger, Displace and Grapple Shot give you positioning and reach, and Desecrate can strip a hostile site effect entirely when an Evil ally connects with it.

Mulligan aggressively. You want two or three sites and something castable before turn four, ideally one of your ramp pieces or a cheap Wizard. A hand with no early play and a pile of six and seven drops is worth sending back even at the cost of a card, since this deck's whole identity is not having to sit still while it waits for the right color to show up.
