Is Keiga, the Tide Star good in Commander?

Keiga, the Tide Star in Commander — Combos, Decks & Price

Keiga, the Tide Star steals a creature when it dies — no attack trigger, no tap ability, just a guaranteed theft on any death — and at six mana for a 5/5 flying legend, the rate is honest. The engine gets absurd with Nim Deathmantle, which lets you loop the death trigger repeatedly, and Sivitri, Dragon Master turns Keiga into a toolbox piece you can tutor on demand.

Format Analysis

Where it lives, where it can’t

Format	Verdict
commander	legal
legacy	legal
modern	legal
pioneer	not legal
standard	not legal
vintage	legal
pauper	not legal
oathbreaker	legal

Commander is where Keiga, the Tide Star earns its keep — multiplayer tables guarantee targets worth stealing, and the legend rule creates a built-in sacrifice outlet when two copies share the battlefield, turning a drawback into a free trigger. In Legacy and Vintage, six mana for a creature with no immediate board impact beyond a conditional death trigger is too slow against turn-one and turn-two win conditions; the card is legal but effectively irrelevant in those formats. Modern is the same story: the format's clock is too fast for a six-drop that needs to die before it does anything. Keiga sees real play in Commander and nowhere else.
