Greyjoy Soldier

We do not sow (Whenever this creature deals
damage to a player, if that player has more cards in
hand than you, exile the top card of their library.
You may cast that card and you may spend mana as
though it were mana of any color to cast that spell.)
House Greyjoy of Pyke is one of the Great Houses of
Westeros. It rules over the Iron Islands, a harsh and
bleak collection of forbidding islands off the west coast
of Westeros, from the Seastone Chair in the castle
of Pyke.
