Any time a creature has more than one Role controlled by the same player attached to it, the creature keeps the newest Role and all the others controlled by that player are put into the graveyard (and then cease to exist as they're tokens)
It's a way to bring a fresh new look to spells that are legal in a variety of formats
New game mechanics may be added, such as the new Location cards coming to February's Into the Inklands set and possibly other surprises along the way
The deck starts by playing number of efficiently costed, strong outlaw creatures with powerful abilities when you commit a crime (targeting opponents, anything they control, and/or cards in their graveyards)
These new types of cards are special, stronger mechanics that are introduced and faded out of the game frequently
Booster pack contains 10 cards and 1 Basic Energy
