Zerachiel's Smithy

Play this card only if a player has 4 or more
artifacts in play.
When Zerachiel's Smithy enters the battlefield
you may search your library for an artifact.
Reveal it and if it is an equipment put it onto
the battlefield, if not put it on the top of your
library instead.
Creatures you control have +1/+0 if you control another non enchantment artifact.
