Vaan, Street Thief

Mana cost: {2}{R}

Legendary Creature — Human Scout

Whenever one or more Scouts, Pirates, and/or Rogues you control deal combat damage to a player, exile the top card of that player's library. You may cast it. If you don't, create a Treasure token. Whenever you cast a spell you don't own, put a +1/+1 counter on each Scout, Pirate, and Rogue you control.
