Sentinel Totem

In Commander, Sentinel Totem earns its slot as a repeatable threat check against graveyard strategies — reanimator, dredge, and self-mill commanders all fold to it, and the instant-speed activation means you hold up mana for other responses and use it only when it matters. In Modern and Legacy, it competes with Relic of Progenitus and Tormod's Crypt, where the scry-on-entry is a genuine differentiator but the single-use exile lags behind Relic's incremental pressure. Pioneer has fewer graveyard combo decks of the same caliber, so Sentinel Totem sees fringe sideboard play there but rarely earns a main-deck spot. Across every legal format, the one-mana entry point keeps it relevant as a budget option when the more powerful hate pieces are unavailable or too expensive.
