Hi. I'm fairly new to the game and have been reading forums about how to build certain decks. I've been trying to build a Ravenclaw deck and some threads were suggesting Acid Jet and Shadow Font. However when I checked the Merchant, I could not for the life of me find these cards. They aren't even in the card list in this website. I have seen them though so I'm pretty sure they exist. Anyone care to shed some light on this? I really want to get my hands on these cards! Thanks!
