The main strategy for this deck is to gain as many life points as possible and deal a ton of damage at the same time. The main monster you want to focus on is Guardian Angel Joan who will be a "boss monster" of some sorts, the main 2 ways to get them out is Tribute Burial and Apprentice Piper. Once you have summoned Guardian Angel Joan the next part of the strategy comes into play, use as many equip spells to raise their ATK to a really high number (preferably 3 United We Stand and either 2 Axe of Despair or Mage Power). This will allow you to destroy nearly any monster your opponent summons and gain A LOT of LP. Most of the cards in the Extra Deck are for when you are in a pinch and have no other choice.
Use Different Dimension Capsule and Gold Sarcophagus to search for the cards you need, use Gold Sarcophagus for the more valuable cards.
Use Absorbing Jar in conjunction with Neo-Spacian Air Hummingbird.
