Artifact, 3U (4)
Rare
Players can't search libraries.
Rogue mechanists once rummaged through the wastes of the Tidehollow, constructing unauthorized golems to threaten the hegemony of the sphinxes. The orbs put a stop to that.

10/1/2008: The only difference between a colored artifact and a colorless artifact is, obviously, its color. Unlike most artifacts, a colored artifact requires colored mana to cast. Also unlike most artifacts, a colored artifact has a color in all zones. It will interact with cards that care about color. Other than that, a colored artifact behaves just like any other artifact. It will interact as normal with any card that cares about artifacts, such as Shatter or Arcbound Ravager.
10/1/2008: If an effect says "You may search your library . . . If you do, shuffle your library," you can't choose to search, so you won't shuffle.
10/1/2008: If an effect says "Search your library . . . Then shuffle your library," the search effect fails, but you will have to shuffle.
10/1/2008: Since players can't search, players won't be able to find any cards in a library. The effect applies to all players and all libraries. If a spell or ability's effect has other parts that don't depend on searching for or finding cards, they will still work normally.
10/1/2008: Effects that tell a player to reveal cards from a library or look at cards from the top of a library will still work. Only effects that use the word "search" will fail.
