The first Legion Loot card available with March of the Legion is the Paper Airplane. This is exactly as much fun as it sounds. The code is turned in for the paper airplane manual, an on-use item that creates either paper zeppelins or paper gyrocopters. It's a 50/50 chance which one you'll get. What's the point of these? Why paper airplane fights of course! Throw them at your friends, and best of all, since you can keep several in your bag at once, you can throw a bunch at once and no one will suspect a thing until they see them soaring through the air.
My favorite of the cards has to be the Robotic Homing chicken. This is the third non-combat pet available from the TCG, and personally, I find these to be some of the best pets in the game (Murky topping the list, of course.) The card itself is pretty explosive, so I imagine the pet will be as well, considering it's a mechanical chicken with freakin' rockets strapped to its back. How cool is that!
The last Legion Loot card finally answers that question: what was the dragon kite model for? I was thinking they were preparing for another holiday event, but as it turns out, it's a loot item from a card appropriately named "kiting." The kite, shaped to resemble Onyxia, will tag behind you, and I'm told it's idle animation includes a cloud forming above it to strike the little dragon.
While I have yet to be lucky enough to get a loot card from any of the previous TCG sets, I am crossing my fingers that this will be my turn. Which loot card do you think is the coolest?
