Earwig Squad is a rare Creature — Goblin Rogue card from Magic Online Promos (PRM), collector number 32539.
Prowl {2}{B} (You may cast this for its prowl cost if you dealt combat damage to a player this turn with a Goblin or Rogue.) When this creature enters, if its prowl cost was paid, search target opponent's library for three cards and exile them. Then that player shuffles.
