When Cave of Wonders enters the battlefield, you may search your library for a card named, The Lamp. If you do, reveal it, and put it into your hand.
You may cast The Lamp as long as you control any creature named, Aladdin, without paying it's mana cost.
If a different artifact would come into play under your control, sacrifice it and Cave of Wonders.
