I generally start off the game by drawing 100 of everything useful for everyone, but later on it becomes predominantly refining. However, I'm playing differently right now (LOTS of Triple Triad in the beginning and minimal leveling), so I don't have the spells I normally would this early (-agas, Flare and Holy from Diablos, etc.)...but as soon as Quezy learns Card Mod, I have over 300 cards ready to be turned into gamebreaking spells.
