Earwig Squad

Surgical library extraction is rare in black, and rarer still bolted to a creature with a clock attached. Cast it the hard way and you get a 5/3 with no rider, a body that trades up and dies to almost anything. Connect first with a Goblin or Rogue, pay the cheaper prowl cost, and the same creature arrives with a heist trigger: dig three cards out of an opponent's library and exile them before they can be drawn. That conditional is the whole transaction. The search only fires if the prowl cost was paid, so a combat step has to be won before the deckbuilding battle is. The trade-off cuts both ways: prowl turns this into a play, exactly what an aggressive shell wants, but it cannot drop the body and connect on the same turn, so the disruption always lags the beatdown by a turn. By the time it comes down for its prowl cost, the board already did the work of earning the trigger. The reward is steep precisely because the entry fee is a connection your opening turns may not afford. Strip three combo pieces or a sweeper out of a deck you already have pinned down, and the 5/3 becomes almost incidental to the theft it carries in.
