I like amiibo, and support it. How they are used in BotW, Smash, Mario Kart, Twilight Princess HD, etc is perfect in my opinion. Nice collectibles with added functionality.
However putting an entire game mode behind it like this is just wrong. Keep it small, and this should be available from with thw Vanilla game. Heck it would even sting less as paid DLC because there won't be supply constrictuons, though it still wouldn't be right.
