: Search your library for a legendary card, reveal that card, put it into your hand, then shuffle.
Captain Sisay turns every tap into a tutor for any legendary card, letting you assemble a toolbox of legendary creatures, planeswalkers, and powerful Legendary spells. Protect Sisay, untap her repeatedly, and chain into a value engine or combo piece that closes the game. You play a midrange GW shell that grinds incremental advantage until you find your win.
Repeatable, color-agnostic tutoring for any legendary card every turn
Access to the deepest pool of legendary bombs, planeswalkers, and silver-bullet answers
Untap effects make her a combo and value engine
GW gives strong ramp, recursion, and protection for the commander
Slow without untappers or haste—she needs to survive a turn cycle
Heavily reliant on Sisay; removal-heavy tables shut her down
Tutoring one card per turn can be too slow against fast combo
Restricting the deck to legendary cards limits roleplayers and answers
