Each of the five pre-constructed decks explores a different theme related to the Commander card in their deck. "Call the Spirits", features Daxos the Returned, a Zombie Soldier from Theros who resurrects the dead and brings enchantments back from the grave. "Seize Control" is a Blue/Red deck where the Goblin Wizard Mizzix of the Izmagnus takes power with instants and sorceries. "Plunder the Graves" features a new Human Shaman, Meren of Clan Nel Toth, who gains power when your own creatures die. Kalemne, Disciple of Iroas leads the forces of "Wade into Battle", where the Giant Soldier's army is ready to get into a fight. Finally, a new version of Ezuri, Ezuri, Claw of Progress is the Commander in "Swell the Host, a Blue/Green deck that feels very Simic in its experimentation.
All of the cards printed in Magic: The Gathering-Commander (2015) will be legal in Vintage and Legacy tournaments, but will not be legal for Standard or Modern.
The release of the decklists for the Commander format comes hot on the heels of the announcement of the next set, Shadows Over Innistrad (see "New 'Magic: The Gathering' Set Announced"), due out in April.
