Shawn Ray, Grand Artificier

Whenever you play any artifact with the subtype
"proverb" from your hand,
you may attach it to Shawn.
{4},{t}: Search your library for a artifact
card subtype "Proverb",
put that card into your hand.
When Shawn has four Proverbs attached to him,
at the beginning of each end step,
if its not your turn take an extra turn after this.
