Build me a simple web app for managing a Magic the Gathering collection.

I want to be able to add cards, browse my collection, and organize cards into decks. It should feel like a normal Django site with a clean set of pages, forms, and templates, and it should have a way to import or update card data so I don’t have to enter everything by hand. If it makes sense, add a small dashboard or home page that helps me quickly see what I own and what decks I’ve made.

Please keep it straightforward and usable, with basic search and filtering if you can. Make the app easy to run locally, and wire up whatever pages, models, and URLs are needed so the main collection and deck flows actually work. If you need to check current Django or MTG card data docs online, go ahead.
