Sidisi, Undead Vizier card art
Sidisi, Undead Vizier enters the battlefield and immediately tutors any card in your library — the exploit cost is a feature, not a bug, in any deck running Mikaeus, the Unhallowed or Rooftop Storm to recur her for free. Five mana for an unconditional search stapled to a 4/6 deathtouch body is the deal; the only real cost is that you need a sacrifice target ready on entry.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Commander is where Sidisi, Undead Vizier earns her reputation — a guaranteed tutor on a creature body fits naturally into any black strategy, and zombie tribal specifically treats her as an auto-include. In Legacy and Vintage she's legal but irrelevant; five mana for a tutor that doesn't go to hand immediately can't compete with Demonic Tutor or Imperial Seal at a fraction of the cost and without needing a sacrifice outlet. Pioneer offers a more creature-centric environment where she could theoretically fit a sacrifice shell, but the competition for five-mana payoffs is stiff enough that she rarely sees play there. Oathbreaker is the one non-Commander format worth mentioning — as a signature spell or just as a 99 piece in a black shell, she functions cleanly, though the format's lower life totals reward faster lines.

Budget Alternatives

Cheaper options that do most of the same work

Diabolic Tutor covers the unconditional "search your library for any card" effect for under $1, with no creature body and no exploit upside — you're paying purely for the tutor effect at the same sorcery speed. If the sacrifice synergy matters to your build, Rune-Scarred Demon does nearly the same job as Sidisi, Undead Vizier for roughly $1–2 and doesn't require a sacrifice target, though the seven-mana cost is a meaningful upgrade bump.

Price Context

Current price

$13.28 mid tier

At $13.28, Sidisi, Undead Vizier sits in the mid tier — expensive enough to feel like a budget decision, cheap enough that she earns her slot in any black Commander deck that can exploit the exploit. Demand from zombie tribal, aristocrats, and generic black goodstuff keeps the floor stable; this is a card you buy to play, not to trade away.
