Fifth Column

{4},{t}: You may put a historic permanent card from
your hand onto the battlefield. (Artifacts, legendaries, and sagas are historic.)
"A communist party was in fact a fifth column as
much as any [German] Bund group, except that the
latter were crude and ineffective in comparison with
the Communists". Arthur M. Schlesinger Jr., wrote:
"the special Soviet advantage-the warhead-lies in
the fifth column; and the fifth column is based on
the local Communist parties".
