I think what you're refeerring to is the flare on Joker's finger from where he threw the card, but I don't think he actually ignited it from scratch and it didn't actually show him igniting it, just the after-position of where he threw the card.
 * 3rd Gens can ignite themselves and manipulate fire. Joker can both manipulate fire and ignite himself (ch7,pg10), making him a 3rd gen.
