Try contacting Andrew on Facebook. He's generally pretty open to jamming and helping people. The tips I've heard/worked with are these:
1) Use an old deck. An old, old deck. The sides should be brown. This causes the cards to stick together more so than a new deck, which is helpful. If you have Wynns or thicker-stock cards, try those.
2) The triangle should be comprised of about 5-10 cards each. The top and bottom packets should be the bulk of the deck.
Hope this helps!
