Geist of Saint Thalia

How it plays & wins

Geist of Saint Thalia leads an artifact-heavy blue deck built around fast mana: Sol Ring, Mana Vault, Grim Monolith, Mox Opal, Chrome Mox and Ancient Tomb. It uses that mana to deploy rocks and interact cheaply with Force of Will, Fierce Guardianship, Pact of Negation, Mental Misstep and Flusterstorm. Rhystic Study, Mystic Remora, Timetwister and Paradoxical Outcome keep it stocked with cards, and Mystical Tutor, Fabricate, Transmute Artifact and Tezzeret the Seeker find the key pieces.

The cleanest win is Isochron Scepter imprinted with Dramatic Reversal. With enough mana rocks, each activation untaps them for net mana, which should give a loop of mana and Scepter activations. The list doesn't spell out how that mana becomes lethal, so the finish is not fully clear to me. Aetherflux Reservoir is the most obvious backup. It can gain life as spells are cast and then fire off for damage. I wouldn't claim more than that.
