Been experimenting with Exodia FTK ideas for fun. I know this can improve, but it can be an FTK in most cases as long as you get a Piri or Library in your opening hand with 3 usable spells. Trash 2 of the pieces of Exodia with Magical Stone (for a Golden Bamboo Sword) and get them back with Mass Production. Your 2nd Magical Stone (again ideally bringing back a Golden Bamboo Sword) can trash unusable cards and/or a Cursed Bamboo. Use Foolish Burial for a Cursed Bamboo Sword. As long as you follow those rules, you'll probably win in about 3 out of every 5 games that you start first, in my experience. I've even gone on runs of as much as 10 wins in a row with this deck.
In Master Duel, an ideal win will usually end with 6,000+ xp, MUCH higher than typical (just don't expect to rise through the ranks with this deck all that much).
