diablos' card
Diablos' card is non elemental and very powerful (lvl 9 card!) when used in the top left corner of the Triple Triad table. You have no idea how many card games I won because of this card! (Makes Gilgamesh's card easy to get.... <-- worth getting, because it will refine into 10 Holy wars <-- invisible to enemy <-- kill weapons easily. So play the game, and use diablos' card!)You can get it by defeating Diablos in battle and it can be refined into 100 Black Holes.
