Rick Harrison, Pawn Star

Whenever you would play a spell, you may cast it for X less, where X is the desired number as long as your opponent can also do so for their next card.
I'm Rick Harrison and this is my pawn shop. I work here with my old man and my son, Big Hoss. Everything in here has a story and a price. One thing I've learned after 21 years - you never know what is gonna come through that door.
