Tasigur, the Golden Fang

In Commander, Tasigur, the Golden Fang pulls double duty as an efficient beater and a late-game value engine — his activated ability is most punishing in longer games where you can structure your graveyard to guarantee useful returns regardless of which card an opponent picks. In Legacy and Vintage, he's a one-mana 4/5 in shell games where the graveyard fills fast, competing with Gurmag Angler for the same delve niche; Tasigur trades raw clock speed for the upside of his activated ability in longer matchups. Modern sees him as a fringe threat in midrange and control shells, though the format's speed limits how often his recursion loop comes online before the game ends. Pioneer is his weakest competitive home — the format's graveyard hate density and faster threats leave him as a budget beater rather than a true engine.
