This is a Esper control deck that casts noncreature spells of mana value 3 or more to turn Y'shtola into a repeatable drain, pinging every opponent for 2 and gaining 2 life with each one. A suite of counterspells, removal, attack taxes and opponent-tax draw engines keeps the table in check while Y'shtola's end-step trigger and damage-based draw auras refill the hand. Lifegain-to-drain enchantments and creatures turn every point of life gained into a lethal loop, and heavy tutoring finds either that loop or a Thassa's Oracle win. How it wins: It drains the table through Y'shtola and the other pingers, then closes with an infinite lifegain and life-loss loop or by tutoring up Thassa's Oracle with Demonic Consultation or Tainted Pact. Key roles: - Spell-cast drain: Y'shtola and the Wizard-token and Dwarf pingers punish opponents for every noncreature spell cast, while lots of instant-speed 3+ mana value interaction makes each answer double as damage. (Papalymo Totolymo, Cornered by Black Mages, Transpose) - Lifegain-drain loops: Life gained from Y'shtola's triggers is converted into opponent life loss, and pairing a "gain becomes loss" piece with a "loss becomes gain" piece loops until the table is dead. (Sanguine Bond, Exquisite Blood, Vito, Thorn of the Dusk Rose) - Thassa's Oracle combo: Tutors and transmutation assemble a library-exiling spell with the Oracle for an instant win, protected by free counters and Silence-style effects. (Thassa's Oracle, Demonic Consultation, Tainted Pact) - Damage-draw auras and doubling: Y'shtola's ability hits each opponent, so draw-on-damage auras and soulbond draw one card per opponent per trigger, and Delney doubles the triggers of the small-power drainers. (Ophidian Eye, Helm of the Ghastlord, Delney, Streetwise Lookout) - Tax and punisher engines: Opponents are forced to pay mana or bleed life and cards for casting and drawing, fueling card and treasure advantage and Y'shtola's 4-life draw check. (Rhystic Study, Kambal, Consul of Allocation, Sheoldred, the Apocalypse) - Lockdown and fortress: Attack taxes, tapped entries and spell-casting restrictions keep opponents from racing or interfering while the drain accumulates. (Propaganda, Ghostly Prison, Voice of Victory)
