This is a -1/-1 counter deck where Auntie Ool, Cursewretch turns every counter placement into value. Counters on its own creatures draw cards, and counters on opposing creatures drain each controller for 1 per event, so self-blight costs, mass counter sweepers and proliferate all act as both card advantage and reach. Stacked payoffs then multiply each counter event into tokens, life drain, direct damage and stolen creatures. How it wins: It grinds opponents out with repeated mass -1/-1 counter waves, multiplied into drain and damage by payoff enchantments and creatures, while keeping its own board and hand refilled, then finishes with swarms of tokens and stolen creatures. Key roles: - Self-blight fuel: Creatures and spells that put counters on its own creatures as a cost or upkeep tax become steady card draw with Auntie Ool, Cursewretch. Several of these also make Treasure or loot along the way. (Sinister Gnarlbark, Gutsplitter Gang, Devoted Druid) - Mass counter sweepers: Symmetric counter effects hit every creature at once. Each affected creature triggers separately, so one sweep both wipes opposing boards and pays out across many triggers. (Black Sun's Zenith, Carnifex Demon, Soul Snuffers) - Wither and proliferate amplifiers: Wither sources turn ordinary damage into counters, and proliferate re-places counters on every creature and re-fires every placement trigger. (Everlasting Torment, Yawgmoth, Thran Physician, Contagion Engine) - Counter-trigger payoffs: These turn each placement into tokens, life drain or burn aimed at opponents, and they stack with the commander's own triggers. (All Will Be One, Nest of Scarabs, Obelisk Spider) - Death-and-steal engine: When countered opposing creatures die, these cards draw cards, chain more counters, or reanimate the victims onto its side. The Reaper's steal works only once per turn. (Necroskitter, The Scorpion God, Blowfly Infestation) - Undying sac loop: Mikaeus, the Unhallowed gives undying to non-Humans. Their +1/+1 and -1/-1 counters cancel out, so creatures keep returning, and Yawgmoth, Thran Physician's sacrifice ability can repeatedly ping, draw and drain. (Mikaeus, the Unhallowed, Yawgmoth, Thran Physician, Necrotic Ooze)
