Onslaught
Onslaught is the twenty-eight Magic expansion and was released in 2002 as the first set in the Onslaught Block. It had a theme that focused heavily on "tribal" cards or cards that care about creature types.
This features 5 mono-colored "Pitfighter" legends: Rorix Bladewing, Jareth, Leonine Titan, Arcanis the Omnipotent, Silvos, Rogue Elemental, and Visara The Dreadful.
It also has lands that come into play tapped or can be cycled.
Famous cards include Visara The Dreadful, Quicksilver Dragon, Kamahl, Fist of Krosa, and Gravespawn Sovereign.
