The best way is to build your rank just a touch so you can have access to the fairy packs
that are sold on satudays at the shop. Buy at least 25 packs of them to be sure you have
enough. Then build a fairy deck. Make sure it has cards like Spirit of the Breeze, Dancing
Fairy, Absorbing Kid of the Sky, Rain of Mercy, Dian Keto, Cure Mermaid, etc. Then, if you
haven't become a DropOut Boy yet, do so by failing a whole exam. Then duel Prof. Fontaine
with the fairy deck and use every healing power and ability possible. By the time the duel
ends it should be guaranteed a sum of over 10,000 DP, if you play your cards right that
is. Good Luck! (Note 1: The one fairy you DO NOT want in your Fairy Deck is Keldo. It
takes 2 cards from opponents graveyard and shuffles them into deck.; Note 2: Make sure to
have a Spirit Barrier and the Santuary in the Sky to protect your life points only while
you have monsters on the field. But against Prof. Fontaine, that shouldn't be a problem!
