Ever notice how sometimes people show up to tournaments with decks including 5 Vaders, 4 Tarkins, or 3 Obi-Wan's? These decks insure that at least one copy will be down. So what does that mean? There are more copies circulating in the deck to be drawn as destiny. Now here's where Chasm or Abyss comes into play. Whenever a unique card that is already in play on the table, the destiny is reduced to 0 and lost. If it is a character, it loses immunity to attrition and you must lose the character or 2 force. This is extremely useful in a number deck with Figrin D'an. You bring up the insert cards fairly quickly plus your opponent is drawing 2 destiny and bringing up those unique characters. Make sure that your deck won't be severely affected by this, as it affects both players. Try it out and see if it fits your style. Good Luck.
