Other than winning more so you get more chances to spin... no :p Certain FGs are more likely to give out cards, though, due to the proportions of cards in their deck. An FG like Rainbow or DreamCatcher, who have one or two of a whole bunch of different cards are hard to win things from, whereas one like Jezebel or Decay give out cards a lot more, because they have small decks with a lot of 6-ofs. So, in theory, if you design a deck that consistently beats FGs who statistically give out more cards per win like those ones, you could increase your odds, but the spin itself is still 100% random.
