If a creature an opponent controls would die, exile it instead.
At the beginning of your upkeep, put all creature cards exiled with Gisa onto the battlefield under your control. They gain decayed. (A creature with decayed can't block. When it attacks, sacrifice it at end of combat.)
Gisa exiles your opponents' creatures as they die, then reanimates them all under your control each upkeep as decayed (attack-only, sacrifice-at-end) tokens. You leverage forced sacrifice, board wipes, and removal to feed Gisa, then weaponize the stolen army through aristocrats payoffs, removing the decayed downside, or swinging for lethal before they sacrifice.
Add edict and forced-sacrifice pieces (Grave Pact, Dictate of Erebos, Butcher of Malakir) so you control when creatures die rather than waiting on opponents. Layer in aristocrats drain (Blood Artist, Zulaport Cutthroat, Bastion of Remembrance) plus Treasure/death payoffs like Pitiless Plunderer to convert sacrifices into ramp and damage. Tighten the manabase with fast mana (Dark Ritual, Jet Medallion), top-end tutors (Demonic Tutor, Vampiric Tutor), and protection like Imp's Mischief or Heroic Intervention to keep Gisa online.
