Eddard, Hand of the King

Parley - {t}: Each player reveals the top card of his
or her library. For each nonland card revealed
this way, create a colorless artifact token named
Gold with "Sacrifice this artifact: Add one
mana of any color to your mana pool" and
add a stress counter to Eddard, Hand of the King.
When Eddard, Hand of the King has ten or more
stress counters, sacrifice Eddard, Hand of the King.
