Card Tips:Crystal Pair


 * This card is useful in two ways--first, if you only control one monster but your opponent controls many monsters, activating this card will allow you to keep from taking additional damage. Secondly, if you choose a different monster to go into your Spell & Trap zone than the one that was sent to the Graveyard (or already existed in the Graveyard) you're one step closer to the requirements for Rainbow Dragon.
