Unearth is attractive in Commander because it lets black decks cheaply recur small creatures with strong enter-the-battlefield effects. The cycling mode keeps it relevant when there is no target, which adds consistency over a long multiplayer game. It is especially popular in value, aristocrats, and graveyard-centric strategies that lean on efficient three-mana creatures. The card’s flexibility and low mana cost make it an easy include in grindy black lists.
