When your opponent has no more Seals left, you can order a Seal to attack to your opponent's Hand. Your Seal can attack a Seal or Mystic in your opponent's Hand, and that card immediately goes to the Shrine without calculating the At, Df, Sp, etc. You can Attack to your opponent's Hand once per Turn.
Some Seals have Skills/Abilities that can make them Attack to Hand, although your opponent have Seal(s) on the Arena such as Damita Queen .
