Artifact, 3 (3) {0}: Tap all lands you control. Chimeric Idol becomes a 3/3 Turtle artifact creature until end of turn.1 After a chimeric idol attacked them, the Keldons smashed all unfamiliar statues.
Illus. Mark Tedin
10/4/2004: Your lands are tapped as part of the effect, not part of the cost.
8/1/2008: A noncreature permanent that turns into a creature is subject to the "summoning sickness" rule: It can only attack, and its {T} abilities can only be activated, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
