Onslaught (ONS)

Onslaught is a Magic: The Gathering expert-level block. It consists of the expansion sets Onslaught (October 2002), Legions (January 2003) and Scourge (May 2003). The block's main theme is creature types (for example, Clerics and Goblins), and much of the game play concerns interactions between these "tribes".
