Tonks crinkled her nose playfully. "Well, You use a dragon poker deck. Which, of course, has less cards than your normal Muggle deck."
She quickly moved from her comfortable place on his shoulder. It would be back when she needed it. Flipping completely over to look under couch, she about fell over again. As she started to throw things out from underneath, she came across her pygmy puff that she had lost. Giggling, she tickled it and moved on. Papers and random quidditch souvenirs flying threw the air as she searched for her deck. Finally she found them, hiding underneath a book she didn't remember ever seeing before.
"I found them!" As she attempted to flip back up Tonks fell backwards onto the floor. She placed the deck beside Regulus and climbed back onto the couch.
"Ok... Your deck goes Wizard, Baron, Count, Prince/Princess, Queen, King, Dragon. If you get a Wizard you can pay, or in this case take a shot, to get an extra card. If you get a Count you can pay to have it made a wild. You never look at your cards and you only get 7 unless you get a Wizard, of course. The point is flip over as many cards to bet the other person." She transfigured a book into a small table for them to play on and accioed several bottles over.
