📖 How to build Ghoulcaller Gisa
Ghoulcaller Gisa turns creatures you no longer need into an army. Each activation costs {B} and taps her, and you sacrifice another creature to create X 2/2 black Zombie tokens, where X is that creature's power. The game plan is to sacrifice high-power creatures for large numbers of Zombies, building a wide board while keeping Gisa herself active each turn.
Build around high-power creatures that are good to sacrifice, and around ways to get them into the graveyard or onto the battlefield quickly. Dark Ritual and Demonic Tutor can speed up casting Gisa and finding her. Reanimate can return a big creature as fodder. Victimize, Deadly Dispute, and Feed the Swarm help turn opposing or your own creatures into sacrifice value. Blood Artist fits the sacrifice theme, and Phyrexian Arena or Black Market Connections can add card advantage to keep feeding her.
Gisa has clear weaknesses. She taps, so she produces at most one activation per turn, and she needs another creature to sacrifice, so an empty board stalls her. Her tokens are always 2/2 regardless of the sacrificed creature's power, so low-power fodder wastes her ability. As a single legendary creature she is vulnerable to removal, and a sweeper like Toxic Deluge will wipe your own sacrifice fodder along with the opposition.
