refining the gilgamesh card must be one of the best things i've ever done. although i haven't gotten to using any of the holy wars yet. thought maybe i'd use it against ultima weapon or something. all i recommend is getting EVERY type of card you can. once you have every card (and multiples of every card, becasue sometimes you need to more than one to refine things) you won't have much of a reason to play with the cards anymore, and that's when you know that you can start refining.
