Earwig Squad
Creature — Goblin Rogue
Prowl 
(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.

The cards are exiled face up. All players will know what they are.
