I don't understand how this 6-pack deal for Ondrej's Blue Butterfly cards are still in stock at Penguin. I had stocked up on a ton of Red Butterfly decks last year because the Blue ones were sold out everywhere. Now the Blue Butterfly's are back in stock and what a deal for a 6-pack!! This deck allows me to do things I simply cannot do with a Bicycle deck-- or even a marked Bicycle deck-- have the spectator mix up the cards and then hand them back to me-- then tell them to just NAME a card--- not pick a card-- so much more powerful to start off a card effect just saying -- name any card--and you can proceed to cut that card to the top or bottom of the deck and go from there with what you want to do. Also the ability to turn your back while they place their chosen card back into the middle of the deck somewhere and you instantly know what card it is, and exactly where in the deck-- This deck is pure gold. I have bought more bricks of these than I could ever count.
