Forum:Crystal Beasts Deck

I recently ran into a thread,

http://www.pojo.biz/board/showthread.php?t=517383,

and found it interesting that Rainbow Dragon usually does not have a purpose being in certain Crystal Beast Deck. Should we add Rainbow Dragon anyway (in case we got ourselves into a bad situation) or should we not and add other cards like Hamon?

+When you enter the website I posted, there should be a signature on alexhwangxp's box that sends you to his youtube video about his Crystal Beast Deck. Just letting you all know..+
