This deck perfectly works to get high score from Legendary Duelists (LDs) below.
Start the duel by using the skill to build a labyrinth to stall the duel, shuffling 2 cards that you don't need early in the duel.
Once you have your labyrinth set up, keep using any/all the cards that you have that can help with drawing more cards.
While there really isn't an order to using the spell/trap cards, there are a list of things to do in order to execute it properly.
This deck can be used against Mai, but you will have to play it differently.
