Creature - Goblin Rogue 2/1, 3B (4) Prowl {1}{B} (You may cast this for its prowl cost if you dealt combat damage to a player this turn with a Goblin or Rogue.)
Whenever a Rogue you control attacks and isn't blocked, it gets +2/+1 until end of turn.1
Illus. Brandon Dorman
4/1/2008: This ability triggers after blockers are declared during the declare blockers step. Each attacking Rogue you control gets +2/+1 if no creatures were assigned to block it. That creature will get the bonus even if an effect causes it to become blocked.
