In the Apocalypse cardset, we saw the deaths of several characters that had been part of the Magic storyline for years. The Phyrexian invasion of Dominaria left the entire multiverse in dissarray. The odyssey of the Skyship Weatherlight and its crew is now over, and a new odyssey has begun. It is now 100 years after the Phyrexian invasion, and the inhabitants of Dominaria are struggling to survive. The new storyline takes place on a continent called Otaria, where deadly pit-fighting is a part of life. This may explain why the Odyssey cardset is all about the graveyard --- but that's not such a bad thing.

Odyssey introduces two new game mechanics: Threshold and Flashback. Anytime that a player has seven or more cards in his graveyard, he has Threshold. Many spells in this set become stronger (read "broken") if their controller has Threshold. The other mechanic, Flashback, allows you play a spell from your graveyard as though it were in your hand, but for a different casting cost. When you play a spell using Flashback, you have to remove it from the game as soon as it's done resolving.

Another interesting feature of Odyssey is that it takes protection to a whole new level. Rather than just having protection from a specific color or creature type, there are cards that have protection from all colors, all creatures, and even a few that have protection from instants and sorceries!

Notable Cards
Mirari Buy has caught the attention of pretty much everyone that has even glanced at this set. It's ability is incredibly close to that of Fork Buy, which was banned in Extended format because it is so powerful. You can expect to see a lot of decks trying to abuse this card.

Other cards that have players drooling all over their Ultra-Pros include Vampiric Dragon Buy, Iridescent Angel Buy, Traumatize Buy, and Haunting Echoes Buy.
