This deck is a burn deck that focuses on healing yourself, while quickly reducing the opponent's Life Points to 0.
The main strategy of the deck is to get Fire Princess out as soon as possible and protecting her from any attack and get out cards to heal. The deck then uses card effects that heal yourself, and then inflicting 500 damage to opponent via Fire Princess effect. The deck has fast burning.
The strength of this deck is that it's completely safe from cards such as Mirror Force, Dimensional Prison, Sakuretsu Armor, etc. The other strength is that with so many heal cards, this deck can achieved an OTK if have the right cards on hand. The healing card increases your life point and reduces the opponent, widening the gap between you and your opponent.
The weakness of this deck is that Fire Princess Attack Points and Defense Points is weak, therefore, it needs cards like Messenger of Peace or Gravity Bind to protect it. Another major weakness for this deck are card destroying cards like Heavy Storm (recently made limited again), Mystical Space Typhoon (Unlimited), Scrap Dragon, etc. Overall, this deck relied heavily on stalling the opponent, therefore, if the set up is too slow, your opponent gains a huge advantage.
