MagCorio with Miraidon is a solid list, and one I highlighted in today's article. That being said, I cannot believe how Master Plan hasn't caught on yet in Magnezone decks. Double confuse means a 25% chance to get through to you. Master Plan also acts as a pseudo-clear for sleep and paralyze for yourself, as hitting tails on your flip of the card overrides both for confuse for your active, which I'd prefer over the other options. Try it out and let me know what you think on Discord!
