The Commander

Sisay gets +1/+1 for each color among other legendary permanents you control.

{W} {U} {B} {R} {G} : Search your library for a legendary permanent card with mana value less than Sisay's power, put that card onto the battlefield, then shuffle.

Guide

Gameplan

Sisay is a WUBRG toolbox commander: assemble multiple legendary permanents to pump her power, then use her five-mana activated ability to repeatedly tutor legendary permanents directly onto the battlefield. You snowball into a chain of legendary creatures, planeswalkers, and artifacts that either lock the table out or assemble a combo.

Strengths

On-board tutoring lets you fetch the exact answer or combo piece each turn without spending cards.
Access to all five colors means the best legends, ramp, and interaction in the format are available.
Self-scaling power: more legends means a bigger Sisay and access to higher-MV tutor targets.
Extremely flexible toolbox—silver bullets like Drannith Magistrate, Karn, the Great Creator, or Teferi answer almost anything.

Weaknesses

Heavily commander-dependent; repeated removal or graveyard hate on combo pieces shuts the engine down.
Five-color mana base is greedy and expensive, prone to color screw without strong fixing.
Activation costs WUBRG plus needs enough power to hit relevant targets, so it can be slow to come online.
Telegraphs combos—savvy tables will hold interaction for your tutor chains.

Key Cards

Thassa's Oracle — Combo finisher you can tutor up alongside a way to empty your library for an instant win.
Jegantha, the Wellspring — Cheap legend that adds five colors of mana, helping pay Sisay's WUBRG activation repeatedly.
Karn, the Great Creator — A tutorable legendary that locks opposing artifacts and fetches your own from sideboard-style toolbox.
Drannith Magistrate — A legendary creature that shuts off opposing commanders and tutor-on-board strategies.
Sphinx of the Steel Wind — Not legendary, but the kind of high-impact body Sisay decks lean on; prioritize legendary equivalents like Avacyn.
Captain Sisay — Backup tutoring engine that fetches any legend regardless of power, smoothing your toolbox.

Upgrade Path

Tighten the mana base with all relevant fetches, duals, and Triomes plus fast mana like Mana Crypt, Jeweled Lotus, and Mox Diamond to accelerate Sisay and her WUBRG activations. Add a compact, tutorable two-card combo (such as Mikaeus, the Unhallowed plus a free sac outlet, or a Thassa's Oracle/Demonic Consultation package) so every tutor builds toward a kill. Round out with protection like Heroic Intervention and Lightning Greaves and efficient stax bullets to defend the engine while you set up.
