Rate my Crystal Beast Deck?

First the monters. Magical merchant will kill more than it helps due to the large amounts of monsters. You should really only use it in a chimeratech or a speed deck.. add in a topaz tiger to replace it. Next the spells and traps. get rid of creature swap for another lighting vortex and then take out threatening roar for a mirror force if you have it. If not replace it with a rainbow ruins. ^_^ hope this helps
