Cosmic Power (Claydol - Great Encounters)
Q. Can I use Claydol's "Cosmic Power" Poke-POWER if I already have more than 6 cards in my hand?
A. Yes, you can. If you have 6 or more cards in your hand after putting 1 or 2 on the bottom of your deck, you simply do not draw anything at that point. (Feb 21, 2008 PUI Rules Team)
