Olinda turns opponents' own creatures into upkeep life-loss engines. Each time she enters or attacks, she marks one creature per opponent with an odor counter that drains its controller 2 life every upkeep, and the counters stay after she leaves. The deck surrounds her with ways to re-trigger her entry and repeat her attacks: blink, death-and-return tricks, myriad copies and evasion. It also gives opponents creatures to mark, and stacks static punishers that bleed the table for drawing, casting, playing lands and having creatures enter. How it wins: Odor counters, punisher effects and drain triggers grind every opponent's life down in parallel, finished by Exsanguinate, Blood Artist drains or evasive attacks. Key roles: - Gifted creatures and tokens: These give opponents bodies, so Olinda always has a target to mark. Some are themselves upkeep-damage permanents, and their entry punishes the receiving player through enter triggers. (Sleeper Agent, Hunted Horror, Akroan Horse) - Re-triggering Olinda: Blink, end-step flicker and "dies, return to the battlefield" instants re-trigger Olinda's entry for fresh odor counters. The same effects protect key creatures and turn sacrifice outlets into value. (Conjurer's Closet, Supernatural Stamina, Kaya's Ghostform) - Attack enablers: Equipment and lands that keep Olinda attacking safely and unblocked. Myriad copies each trigger the attack ability, marking more creatures in one combat. (Blade of Selves, Whispersilk Cloak, Rogue's Passage) - Punisher drain package: Static effects that make opponents lose life for drawing, casting noncreature or nonblack spells, playing lands, or having creatures enter. These pair with the gifted creatures and with symmetrical draw. (Underworld Dreams, Polluted Bonds, Gideon the Oathless) - Sacrifice and aristocrats: Free sac outlets, recursive fodder and death payoffs that drain and draw. They combine with the return-on-death instants for repeated value. (Viscera Seer, Blood Artist, Reassembling Skeleton) - Life as a resource: Heavy pay-life card draw and Phyrexian mana fuel the deck. Lifelink and drain effects offset the cost, ending in a big Exsanguinate. (K'rrik, Son of Yawgmoth, Phyrexian Arena, Exsanguinate)
