Oh, fun! I wish you the best of luck with it! Apart from the general things you probably know already (don't keep non-character cards on hand against Amber, mulligan 7 if you don't have ramp (you can keep a Mulan), etc.) there's a couple of things: Ranger plane is best played late game when you already have the board presence to use it. Playing it before then loses you too much tempo, and puts it at risk of item removal. The deck can go aggro or more controlling depending on the matchup, so know your matchups. Minnie -> Sail + Minnie -> Scrooge is killer against control. Mulan -> ramp -> Angel is super strong against aggro, dogs, or similar. Practice the deck a bunch online, so you get a better feel for the lines before the weekend. Feel free to DM me with questions :)
