Considering you have most of the good cards, how do you play Triple Triad? I do something like that:
A x B
x x x
C x D
A = Diablos Card in Disc 1, Seifer Card afterwards
B = Sacred Card
C = Selphie, Odin or Tiamat Card
D = Minotaur Card
The fifth card is a card that can get cards by three sides. In Disc 1 I use Angelo or Zell, afterwards I use Quistis.
What about you? XD
