The Commander

{T} , Sacrifice a creature you control with mana value X other than Sidisi: Return target creature card with mana value X plus 1 from your graveyard to the battlefield. Activate only as a sorcery.

Guide

Gameplan

Sidisi turns your graveyard into an upgrade engine: sacrifice a small creature to reanimate one a mana value higher, then sacrifice that to climb to even bigger threats. You self-mill or discard fatties, deploy cheap fodder, and use the tap ability each turn to ladder up into game-ending bombs while generating death/ETB value along the way. Close games by chaining into a massive payoff that takes over the board.

Strengths

Only two mana and abuses your graveyard, so it's resilient and cheap to recommit after removal.
Reanimation that dodges sorcery-speed bans on big spells—no need to cast or pay full reanimation cost.
Strong synergy with sacrifice/aristocrats payoffs and ETB/death triggers as you ladder up.
Mono-black gives access to the format's best tutors, recursion, and ramp (Cabal Coffers, dark rituals).

Weaknesses

Ability is sorcery-speed and only reanimates one creature per turn, so it's slow against fast combo.
Needs both fodder and a stocked graveyard, making it vulnerable to graveyard hate (Rest in Peace, Bojuka Bog).
Mono-black struggles to interact with enchantments and noncreature permanents.
Relies on tapping Sidisi—summoning sickness and removal on her stall the engine.

Key Cards

Gravecrawler — Recurring one-drop fodder you can resacrifice every turn to fuel the reanimation ladder.
Bloodghast — Free, repeatable sac fodder that returns whenever a land enters, perfectly feeding Sidisi.
Buried Alive — Stacks your graveyard with the exact creatures you want to ladder into.
Razaketh, the Foulblooded — A top-of-the-ladder payoff whose tutoring locks up games once reanimated.
Grave Pact — Turns your constant sacrificing into board-wide removal and an aristocrats engine.
Bolas's Citadel — Pays off the graveyard/life theme and helps you flood the board with fodder and threats.

Upgrade Path

Add fast mana and rituals (Dark Ritual, Cabal Coffers, Nykthos) to deploy Sidisi early and protect her with Swiftfoot Boots. Tighten the reanimation ladder with recursive fodder (Gravecrawler, Reassembling Skeleton) and high-impact targets at each mana value so every activation matters, then layer in aristocrats payoffs and tutors (Demonic/Vampiric Tutor, Entomb) to assemble a deterministic loop or combo finish.

Aristocrats — Constant sacrificing for the ability fuels death and sacrifice payoffs like Blood Artist and Grave Pact.
Sacrifice Combo — Loops of recursive fodder and reanimation targets enable engine and combo finishes.
Mono-Black Midrange — She slots into a value pile leveraging black's tutors and recursion to grind opponents out.
