Artifact, 1 (1) {X}{1}: Chimeric Coils becomes an X/X Construct artifact creature. Sacrifice it at the beginning of the next end step.1 The energy that infuses the rings with life also melts them away, leaving only useless puddles of slag.
Illus. Michael Sutfin

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.
