Attack Grand Prix Special Rewards

This Attack Grand Prix has special rewards set up. The contents are as shown in the image, and it's the Deep Snow CAD obtainable at the event exchange, but with a custom part attached. It's simply a higher-tier version of the one from the exchange, so don't forget to challenge and grab it! After calculating, it seems I only need to place in the top 10 eight more times, so I'll keep trying!
