Themes and mechanics
The Theros block has two mega cycles.
There is a Mirrored pair spanning two sets in Returned Centaur and Forsaken Drifters. Both are Zombie cards for that mill for four cards. However, Returned Centaur does this when he enters the battlefield and can force an opponent to do so, while Forsaken Drifters do it when they die and it will always be its controller who mills. Also, Forsaken Drifters is 4/2 while the Returned Centaur is 2/4.

The Hero’s Path is a players' event spanning the complete Theros block.  It captures the unique feel of the the mythological Hero and parallels Elspeth's quest in the storyline. Players can participate in the Hero's Path during prerelease events, FNM release events and Game Days. In each of the nine quests of the Hero's Path, they may win an unique Hero card.
