Gisa and Geralf

The sibling necromancers were always going to share a card eventually, and the design problem was how to make two leaders fit one casting cost without picking a favorite. The solution splits the labor cleanly: the mill-four trigger is Geralf's reanimator fuel, stocking the graveyard the moment the body lands, while the once-per-turn recast from the yard is Gisa's relentless army, turning every dead Zombie into a renewable spell rather than a one-time reanimation. That recast clause is the part worth studying. It is not reanimation in the usual sense (no Reanimate-style cheating of mana value), but a recurring permission to cast a Zombie creature from the graveyard, paying full freight each turn while the mill keeps refilling the yard. What holds it back from spiraling is the timing fence: once per turn, your turn only, sorcery-speed in practice. Loosen that single restriction and you would have a value engine capable of burying an opponent in recursion; with it in place, the engine stays a fair grind. And because the loop runs through the graveyard, it lives and dies by what is in the graveyard: a Zombie exiled by hate is a Zombie that never gets recast, so the plan is exposed to the same disruption that any graveyard strategy faces, not insulated from it. The flavor lands regardless. One sibling fills the graveyard while the other empties it back onto the battlefield, a division of necromantic labor the rules text actually models rather than just gesturing at, which is rarer in legendary pair designs than it ought to be.
