■ Castle —Choose one of your shields and attach this card to fortify that shield . When that fortified shield leaves your shields , put this card into your graveyard . (Use " Shield Trigger " abilities before putting this card into your graveyard .)

■ Whenever one of your Aliens leaves the battle zone , you may put an Alien psychic creature that costs less than that Alien from your hyperspatial zone into the battle zone .

■ If the fortified shield isn't fortified by any other castles , whenever the fortified shield would be broken by your opponent 's creatures , you may return one of your other shields to your hand instead .
