Description from the publisher: Guilds vie for supremacy in Ravnica, creating a tenuous balance of power. Jace Beleren, a mind mage who has adopted Ravnica as his home, fights to maintain a delicate peace. But the deadly gorgon Vraska operates by her own arcane moral code. She serves no guild and owes allegiance to none. This assassin-for-hire could destabilize the entire plane … but Jace refuses to let that happen. Each card in these two decks is black-bordered and tournament legal. They were designed to be played right out of the box, with no deckbuilding required.
