Many intro decks are meant to help new players win their first challenge in Magic: The Gathering. These decks usually have only 2 colors. The Vicious Cycle intro deck from the Oath of the Gatewatch has colorless, black, and green cards.
This deck has 60 cards. They split as follows: 25 Lands, 8 Instants, 4 Sorceries, and 23 Creatures. Creature token production and sacrificing creatures for various effects make up the theme for this deck.
If you're a seasoned player, you'll be happy to learn that the Oath of the Gatewatch is the last part of the Battle for Zendikar block. Perhaps many have been waiting for this game expansion to come.
