Severance Priest

In Commander, Severance Priest punches well above its cost: flash lets you drop it at instant speed the moment a Muldrotha or Karador trigger goes on the stack, and the exile effect hitting all graveyards at once covers the table rather than a single target. It won't replace a Tormod's Crypt if you need broad hate, but as a creature-based slot that doubles as a blocker, it earns its place. In constructed formats like Modern and Pioneer, Severance Priest trades generality for precision — it answers one card name at a time, which is narrow against combo decks running multiple graveyard lines. Standard may see it as niche sideboard tech against whatever recursion engine is dominant at a given time, but the flash timing is genuinely strong across all sixty-card formats.
