, , Sacrifice another creature: Create X 2/2 black Zombie creature tokens, where X is the sacrificed creature's power.
Ghoulcaller Gisa turns one big creature into a horde of 2/2 Zombies, then loops those bodies through sacrifice and reanimation engines for incremental value and explosive board states. Early turns ramp and develop a sac fodder base, midgame you activate Gisa on a high-power creature to flood the board, and you close by draining or alpha-striking with a wide, recursive army. It's a mono-black aristocrats/tokens deck that grinds opponents out through attrition.
Generates massive token volume from a single high-power creature, snowballing board presence fast
Mono-black gives access to elite tutors, recursion, and removal for consistency
Excellent synergy with sacrifice payoffs, death triggers, and reanimation loops
Resilient to board wipes since it can rebuild from the graveyard and reactivate Gisa
Gisa is slow: needs mana, a tap, and a creature to sacrifice each turn, and is easy to remove
Mono-black struggles with enchantments and lacks interaction with the stack
Token strategies fold to repeatable board wipes and graveyard hate
Can be mana-hungry and clunky without good ramp and sac fodder online
