Geist of Saint Thalia

How it plays & wins

This is a blue artifact deck built around heavy fast mana: Sol Ring, Mana Vault, Grim Monolith, Moxen, Ancient Tomb, and Mishra's Workshop. It aims to accelerate out a powerful board while holding up free or cheap interaction like Force of Will, Fierce Guardianship, Pact of Negation, Mental Misstep, and Flusterstorm. Rhystic Study, Mystic Remora, The One Ring, and Timetwister keep cards flowing, while Mystical Tutor, Transmute Artifact, Reshape, and Fabricate find the right artifact for the job.

The cleanest win is Isochron Scepter imprinted with Dramatic Reversal. With enough mana rocks, each loop nets mana, giving effectively unlimited mana. Because the Scepter copy is cast, Aetherflux Reservoir triggers each time, so you can gain a huge amount of life and pay 50 to finish the table. The list has other possible routes, but I wouldn't claim a specific one beyond this.
